During startup and uninterrupted operation of an internal combustion engine, a necessary condition is the creation of pressure in the fuel line. This task is assigned to the fuel pumps. They are found on cars and trucks, in diesel and gasoline engines. Some car models are equipped with only one fuel pump, while in other cars two units are installed to maintain a given pressure level. Motorists have to choose a fuel pump in the event of a breakdown of a standard device or in order to increase the power characteristics of the engine. The models differ significantly not only in price, but also in design. To understand this complex issue, you should familiarize yourself with the recommendations of experts.

Diagnostic device

One of the most important tasks in the fuel system of a car is performed by the fuel pump or, as it is called, the fuel pump.
It is he who supplies fuel through the fuel system and a lot depends on him. On injection VAZs, an electric fuel pump is installed, located in the tank. We will tell you in detail how to replace the fuel pump on a VAZ 2110-2112 in this article. Reliable operation of a car of the tenth family directly depends on the condition of the fuel system. The VAZ-2110 fuel pump plays a key role in it. Let's look at typical faults and ways to check this device.

To determine the pressure in the main line, a device is needed. It's easy to do it yourself. You need to take a 10 atmosphere pressure gauge, a fitting and an oxygen hose with an internal diameter of 9 mm. We twist all the elements and tighten them with clamps.

The meter is connected to the ramp. To do this, remove the plastic cap from the end of the tube. Next, use a tire cap to unscrew the nipple.

Bleed off excess gasoline. Before draining the flammable liquid, place a rag to prevent gasoline from getting on the generator. Smoking and using electrified tools near the hood is strictly prohibited.

The free end of the hose is pulled onto the ramp. Secure the clamp. After connecting the battery, turn on the ignition. They take readings. The pressure of the VAZ-2110 fuel pump injector will deflect the pressure gauge needle to 3 atm.

After starting the engine, observe the movement of the needle. On working equipment, the pressure will be maintained within 2.8-3.2 units. If no deviations are found, then the VAZ-2110 fuel pump, injector and regulator are working correctly. It is advisable to remember the characteristics of the equipment.

The pump capacity is about 2 liters per second. If problems arise with the fuel supply, the pump must be replaced. Before checking the pump, make sure that the remaining elements are in good working order. The filter or mesh may be clogged. The fuel filter is changed and the mesh is cleaned.

System pressure

Now let’s talk about how to determine if the fuel pump is faulty. And also about how to diagnose its breakdowns in the early stages. If suddenly all of the above symptoms begin to appear, it is necessary to clamp the fuel return hose to determine whether there is pressure in the system. In this case, it is necessary to perform this action as sharply as possible. As a rule, the maximum pressure value in the fuel rail is about 7 kgf/cm2. On average, a more or less normal gasoline pump shows an outlet pressure of about 5 kgf/cm 2 . In the car's operating instructions you can read that the minimum permissible pressure value is about 4 kgf/cm2. But this is in theory; practice shows that provided that the pump develops such pressure, it can still last for quite a long time. But replacing the VAZ 2110 fuel pump will still be necessary.

Main types

The following fuel pumps are available on the market:

1. Mechanical;
2. Electrical.

The design of a mechanical pump is simple and time-tested. They must have evolved from old mine water pumps that were powered by a steam engine. Automobile pumps are powered by an engine. The electric pump is connected to the generator and battery located in the car, and therefore it is easy to install it immediately inside the gas tank (or along the length of the fuel line).

Pumps also differ in pressure: low pressure, high pressure. The former are usually auxiliary, while the latter are actively used in diesel cars and cars in which gasoline is directly injected.

Hence the following classification: mechanical (used in injection pumps and carburetors), electrical (used in injection pumps and injectors).

How to buy a good quality Bosch fuel pump?

On the market, a Bosch fuel pump costs half as much as mine. I will provide more accurate information, the retail price of a Bosch VAZ 2110 fuel pump on the market or in unscrupulous stores is $10 cheaper than purchasing an original Bosch fuel pump.

I buy it roughly for 300 UAH, from an official supplier and I know that this is the original, and a fake Bosch fuel pump is sold for 220-250 UAH at retail.

The Bosch fuel pump is in a sealed, durable package, the packaging bag is denser than usual, you can feel it. There is purified gasoline inside the package, if you smell it, then the seal is broken, which means there is a chance of corrosion inside the gasoline pump.

Submersible fuel pumps are lubricated and cooled by fuel. Due to low-quality gasoline and additives, internal electrical mechanisms are corroded. When working dry, the brushes overheat and wear out. The service life of the fuel pump is very long.

There were foreign cars that, after more than 25 years, decided to change the fuel pump, only for the reason that it began to pump poorly, such a car was a 1986 Honda Accord 2.0. It was amazing for me to hear when my grandfather, who is also the driver of this car, told me how he tested it.

He says, I take a jar, pour some water, turn it on the battery, I see the stream is weak, and I realized that he is already old. The pump was original, I personally held it in my hands. The pressure created by the fuel pump can reach 6-7 atmospheres; the Bosch fuel pump with the VAZ 2110 operates with this power.

Signs of a malfunctioning fuel pump (gasoline pump)

One of the main signs by which you can safely determine that the fuel pump should be replaced is poor engine draft, in the absence of other visible reasons. Over time, the fuel pump pumps fuel less efficiently, as a result of which the pressure in the system drops, hence the poor engine thrust.

To make sure that the fuel pump is faulty, you should measure the pressure in the fuel system (rail). If the pressure is weak, then the cause is either the fuel pump or the check valve, which is responsible for the pressure in the system.

A faulty fuel pump may make a loud noise, and you will clearly hear the sound of its operation. This may be another sign that characterizes a “dying” pump.

Yes, you can, the fuel pump is constantly immersed in fuel, if there is very little gasoline in the tank or it runs out, the fuel pump will run “idle”, as a result of which there is a high probability of its failure.

Tips and tricks

If it is necessary to replace the VAZ 2110 pump or after removing the pump for preventative replacement/cleaning of the mesh, after completing the reassembly and installation of the pump, do not immediately install the rear sofa and the pump cover.

Additional verification will be required before doing this. To do this, you need to turn on the ignition and determine whether gasoline is leaking from the fuel pipes. Also, the smell of gasoline in the car interior, etc. is not allowed. If this is the case, then you need to determine the cause of the leak and replace the problematic elements, tighten the tube nuts, etc.

To make the selection accurate, the existing module must be removed from the car and purchased a similar one. Also, when choosing, you need to take into account the type of engine, since the pumps are different. Before purchasing, the fuel pump itself should also be inspected, its housing should be checked (cracks, dents, and defects are not allowed).

More about mechanical pumps

Electrically driven pumps perform best. The reason lies in injection engines, which require high pressure and fuel supply to operate without pulsations, causing “starvation” of the engine injectors. When the ignition is turned on, the starter is activated after the pump by 2 seconds.

Electric pumps are lightweight, ergonomic and inexpensive. They are also safe because their operation stops in the following cases:

• An accident has occurred;
• The engine oil level is dangerously low;
• Stopping the engine while the ignition is still on.

Such pumps are most often installed directly inside the gas tank, which ensures isolation from air, high-quality cooling and distance from the engine. It is also possible that it is located further along the fuel line, but this is relatively rare.

There are 3 types of electric pumps:

• Centrifugal;
• Roller;
• Geared.

The most popular are submersible centrifugal ones, the remaining two types can be found in old cars. The reason is the overall reliability and operating features. In centrifugal pumps, liquid can be supplied continuously to the fuel line.

The pumping system itself includes an electric drive and pumping mechanism, a suction tank, a filter and a flow sensor. It also has a safety system necessary to relieve pressure. This system, together with fasteners, can be purchased assembled, or the pump itself can be purchased separately.

Both of the above designs are quite simple. The diaphragm pump is also equipped with a manual pumping lever, due to which the car engine can be started even after a long period of inactivity.

Which fuel pump to choose for replacement

A BOSCH 580454138 fuel pump is installed from the factory. Its service life depends on the quality of the fuel used, as well as on operating conditions. It is also worth noting that this pump is suitable for most other cars, including imported ones. The cost of a BOSCH fuel pump at the moment is from 1,700 rubles. Cheaper analogues are also offered on the market:

• WEBER FP 453-453 from 600 RUR
• ATS 2112-1139010 from 550 RUR
• PEKAR 2112-1139010 from 600 RUR
• FENOX EFP35005O7 from 700 RUR
• HOFER HF 830 301 from 550 RUR
• StartVOLT SFP 0153 from 750 RUR
• VOLTON VLT2112-1139010 from 650 RUR

Any of the above fuel pumps will be suitable as a replacement for the original one, however, not all of them are of the same quality as the original. In addition to the pump itself, you may need a corrugation to replace it, and if the fuel pump mounting ring is damaged, you can order it or purchase it using the following article number:

• Electric fuel pump ring /2110/ metal price from 120 rub.
• Fuel pump corrugation /2110/ 1.5 white from 50 rubles per piece
• Fuel pump corrugation /21101/ 1.6 long from 60 rubles per piece

If you decide to replace the entire fuel module assembly, you can select one of the suggested modules below.

• Electric fuel pump module /21101/ V=1.6 assembled PEKAR price from 2500 rub.
• Electric fuel pump module /21101/ V=1.6 assembled “UTES” price from 3200 rub.
• Electric fuel pump module /21102/ V=1.5 assembled “UTES” price from 3000 rub.
• Electric/fuel pump module /21102/ V=1.5 assembled HOFER price from 2000 RUR

If you decide to change only the fuel pump, we recommend that when replacing it, you immediately carry out a complete inspection of the module - check the check valve and both corrugations, and also, if necessary, replace the fuel grid.

K3 - the best manual fuel pump

The K3 vane pump is used for pumping gasoline, diesel fuel, fuel oil, vegetable oils, as well as alcohol and water. If necessary, it can be used as an auxiliary device for large pumps. Devices made of bronze transport sea water.

The design includes a housing, a shaft, a “wing”, a suction compartment, 4 valves and a lever. During operation, the “wing” on which the valves are installed rotates, resulting in alternate displacement/suction and flow of liquid. Characteristics: productivity 29 l/min, pressure 2.5 atm., suction depth up to 9 m.

Pros:

• multifunctionality and versatility: a wide variety of liquids can be transported;
• high temperature of the pumped substance: up to +80 °C;
• ease of use: easy operation, light weight (10 kg), small dimensions (47x26x25 cm);
• simplicity of design, which indirectly contributes to longevity;
• unpretentiousness in maintenance.

Minuses:

• it is unacceptable to pump liquids with chemical impurities, including carbon dioxide sulfide and ether;
• not cheap (as for a hand pump): 6,850-6,900 thousand rubles.

Determining the replacement time

There are two reasons for pump breakdowns: operating features and wear of the mechanism. In fact, the pump fails for two reasons at once; the only question is under what conditions it worked. And the options could be the following:

• The breakdown occurred due to overheating. An empty fuel tank or a clogged filter are the reasons why the pump simply cannot pump fuel and runs idle, without cooling;
• The cause of the breakdown lies in large solid particles. Actually, a coarse filter is needed to separate debris from fuel;
• Emergency operation of the electrical circuit. Broken wires, short circuits, etc. lead to the pump being switched off by the fuse.

The following will indicate the need to replace the fuel pump as soon as possible:

• The sound of a running engine. Usually this is a noticeable change in the tonality of the sound. The engine is sometimes loud, sometimes quiet (fuel is supplied unevenly). Every motorist knows the sound of his car’s engine, so he will immediately suspect something is wrong;
• The engine has trouble starting. This indicates a malfunction not only of the pump, but also of the battery and starter. You will have to check all devices;
• Engine power dropped noticeably. Try going up a hill - if the car has difficulty negotiating such areas, the problem may lie in the fuel pump.

Let us note here that the fuel pump only reacts to large particles, water and additives in gasoline, which can lead to rapid abrasion of parts and their corrosion. The filter located further along the fuel line is required only by the engine.

Note that a good fuel pump works the entire time you use the car. If it unexpectedly fails and you buy a cheap analogue, you risk having to replace it again.

Checking the electrical circuit

Unlike a carburetor engine, where the fuel pump is mechanically driven, on the injection VAZ 2110/2112 a special relay and fuse are responsible for the operation of this device. Therefore, before moving on to diagnosing the pump itself, it is necessary to check the indicated elements. If any one of them is faulty, the pump will not work at all.

Turn on the ignition without starting the engine and listen. When the fuel pump is running, it emits a characteristic “whistle” when started. If it is not there, it means that either the pump itself has failed, or one of the elements of its power supply circuit has failed.

The pump relay and fuse are located in an additional mounting block located inside the vehicle's center console. It can be accessed by removing the plastic trim (near the front passenger's left foot). It is secured with several screws. Under the cover you will find three relays and three fuses. Typically, the fuel pump circuit protection elements are located centrally.

The relay and fuse are located in an additional mounting block under the cladding

To check the fuse, remove it from its socket and “ring” it with a tester. If necessary, replace it, observing the rating (15 A). It is unlikely that it will be possible to check the relay for functionality without special equipment. But you can take another relay, for example, the radiator fan (far left), and install it in place of the one being diagnosed. Turn on the ignition and listen to see if the fuel pump starts working. If yes, buy and install a new relay. If the problem persists, continue diagnostics.

To check the fuel pump relay, you can install the radiator cooling fan relay in its place.

Instructions for replacing the fuel pump

To begin, move the rear seat to the side and fold back the piece of carpet that covers the fuel module hatch.

Next, unscrew the two bolts securing the hatch and remove it.

A fuel module with two tubes will be visible in front of us.

Before unscrewing the pipes, it is necessary to relieve the pressure in the fuel system. To do this, you will need to remove the fuel pump fuse, or turn off the power to the module and start the engine. After the remaining fuel in the system has been used up, the car will stall and you can begin replacing the fuel pump.

Our fuel module can be of different types - quick-release and screw-on, depending on the year of manufacture of the car. If the fuel pipes are on nuts, unscrew them with a 17mm wrench; if they are on quick releases, then simply tighten the clamps and remove them from the module.

Now, using a 7mm wrench or tube, unscrew the 8 bolts securing the fuel module clamp.

We move the fuel pipes to the sides, lift the clamp and carefully, so as not to spill gasoline, pull out the fuel module.

Disconnect the fuel pump plug

Remove the lock shown in the photo

Using a flat screwdriver, unscrew the two bolts

Remove the rubber bushing and the plastic part underneath it

Now you can remove the fuel pump from the module and replace it with a new one.

To install a new fuel pump and perform assembly, you will need to put a new corrugated hose on the pump. To ensure that this hose does not allow air to pass through, it must be heated when it is put on the pump.

Then we reassemble in reverse order.

What kind of fuel pumps are installed on VAZ 2110/2112 cars

VAZ 2110/2112 cars, depending on the year of manufacture and the type of engine installed, may differ in the method of supplying fuel to the cylinders.

Table: features of fuel supply systems to engine cylinders depending on vehicle modification

Only the first modifications of the VAZ 2110 were equipped with a carburetor injection system. From the factory they were equipped with mechanical fuel pumps of the DAAZ brand (catalog number 2108–1106010). Previously, they had proven themselves well on cars of the Sputnik and Samara series.

A mechanical fuel pump was installed in the engine compartment of the VAZ 2110 to the right of the engine valve cover, and was driven by the camshaft.

All injection VAZ 2110/2112 are equipped with submersible fuel modules. The design of such a module includes:

• electric fuel pump;
• coarse filter;
• fuel level sensor.

The fuel module is installed directly into the vehicle tank. In other words, the gas pump is completely immersed in gasoline. Injection VAZ 2110/2112 were and are equipped with electric fuel pumps of domestic, joint or imported production. These are products of the Utes, Pekar, Saratov plant, as well as the world famous one, the pumps of which are equipped in all modern VAZs. The catalog number of the stock electric pump is 2112–1139009. There are also modifications whose numbers have two additional digits: 02 or 03. Depending on them, products may differ in length and diameter.

Correct operation

Car enthusiasts should wash the coarse filter, which is located in the pump - it quickly becomes clogged with debris from low-quality fuel. It is also important to maintain the fuel level in the tank. If there is too much gasoline/diesel oil, the pump will start to heat up and eventually fail. It is also worth filling up at a gas station with good fuel - you will save not only the engine, but also the pump.

Despite their high resistance to overheating, mechanical pumps can also fail when exposed to high temperatures. Frequent idling is a very common cause of breakdown. One of the simplest methods to solve this problem is to apply a wet rag to the case.

Do not forget also about the “glass” in which the pumping device is fixed. A large amount of dirt and paraffin often accumulates there if you have a diesel car.

We have already said that there are two possible options for installing a fuel pump: inside the fuel tank and outside it. In this case, pumps placed inside the tank have a lock or are sold without it.

To carry out the replacement, you need to have the following on hand: gloves, fire extinguisher, tools. In this case, the best place to work will be a clean, ventilated garage or workshop. After safety, the most important condition is cleanliness. Along with the new pump, under no circumstances should dust, cobwebs or dirt get into the fuel line.

You should look for video tutorials on replacement or find them in test format. In fact, no special skills are needed. If something doesn’t work out for you, use the services of specialists at a service station.

Pressure check

But we should not forget that the automaker wrote all its requirements based on the experiments carried out. If the gas pump does not pump fuel into the system at a pressure of 4 kgf/cm2, then the best way out would be to install a new element. Of course, it is quite possible that the filter at the bottom of the fuel pump has simply never been cleaned. If you replace it, it is possible that the level of pressure created by the VAZ 2110 fuel pump will increase significantly. And it will be quite enough for the car to have normal throttle response and dynamics when driving at high speed. Conventionally, you can carry out a small diagnostic of the fuel pump by disconnecting the fuel line from the ramp. When the power is turned on, a one and a half liter bottle should run to the pump in exactly a minute. Such a check is very relative; it can only be performed if there is no pressure gauge at hand or computer diagnostic systems.

Making a purchase

At an auto parts store, tell the manager the VIN code of your car and ask them to select the original or analogues. The priority is the original, but we will also talk about possible options for purchasing an analogue.

When making your own selection, consider this: the make of your car, model, installed engine, body type. If you are searching online, this is all you need to enter into the search engine. The same is communicated to store managers. This way you will find analogues and original parts. In this case, the geometric parameters of the new pump must be identical to those of the old one. Of course, adapters solve the problem, but it’s not worth complicating an already complex system with a new unit.

Advantages of injection models

The main function of the pump is to supply fuel to the combustion chamber. It must meet certain requirements. The main criterion is pressure.

The pumps for injection and carburetor engines are different. Thanks to the engine with direct fuel injection, there is no need for preliminary preparation of the combustible mixture. As you know, the carburetor is the weak link. Difficult adjustments, clogged jets, difficult starting in cold weather create inconvenience for owners of classic VAZ brands.

Tens and VAZ-2112 internal combustion engines have significant advantages. Let us note the advantages of injection units:

• support for environmental standards;
• direct injection into the combustion chamber;
• fuel economy;
• system reliability;
• increased engine power;
• starting a cold unit without warming up;
• dispensing a portion of the mixture;
• The fuel module is controlled electronically.

Unfortunately, the injector has a number of disadvantages. Maintenance and repairs have to be carried out at a service station. It also requires qualified personnel and a computer to determine the malfunction of electronic components. Let us point out other disadvantages:

• design complexity;
• high requirements for the octane number of gasoline;
• complex diagnostics and repairs;
• expensive spare parts and equipment.

Removing the pumping unit

The VAZ-2110 fuel pump is equipped with an electric drive. Its body is lowered into the fuel tank. Gasoline is both a pumpable fuel and a coolant. It should be remembered that traveling with an empty tank is fraught with overheating of the VAZ-2110 injector fuel pump.

This electrical device is an independent unit. Accordingly, its operation does not depend on the state of other mechanisms. A necessary condition for rotating the VAZ-2110 fuel pump rotor is maintaining normal voltage on the on-board network.

The voltage comes through the ignition switch. When the key is moved to position 1, the circuit is closed to turn on the drive. The VAZ fuel pump fills the fuel rail. The engine is ready to start.

If symptoms of poor fuel system performance occur, the pump should be checked. We list the signs that make it possible to replace the VAZ-2110 fuel pump:

• the car is malfunctioning;
• accelerates poorly;
• twitches while driving;
• won't start at all
• gasoline does not flow to the ramp.

First of all, a hearing test is performed. After turning the ignition key to position No. 1, there should be a noise under the rear seat. The sound lasts for a couple of seconds. This means that the pump has pumped up the required pressure.

Before starting work, you must disconnect the terminal from the battery. This will prevent damage to electrical equipment. In addition, replacing the fuel pump may cause a fire.

Let's prepare tools and materials. To remove the VAZ-2110 fuel pump, you need the following:

1. Screwdriver.
2. 10mm socket wrench.
3. Collar.
4. Open-end wrench 13.
5. Rags.

The device itself is located under the rear seat cushion. To get to the installation location of the fuel pump 2110, you need to remove the seat. Under the casing we find a hatch. We unscrew the hatch. Disconnect the electrical drive connector.

Using an open-end wrench, unscrew the tips of the fuel pipes. We pull off the pipes. Using a spanner, unscrew the 8 nuts around the perimeter of the clamping ring. Release the flange.

There is a gasket under the pressure ring of the fuel pump 2110. The gasket is removed. It is better to change worn tires.

Then we raise the VAZ fuel pump together with the float. Gasoline will leak from the body. To avoid staining the interior, place a rag. There will be up to 1 liter of gasoline left in the old building. Drain it into the tank.

Assembly is carried out in reverse order. There is an arrow on the top of the cover. It should point towards the trunk. This is the correct pump position.

When replacing, do not forget to remove the float and level sensor.

These spare parts are installed on the new structure.

All operations, including preparation, will take less than an hour. After replacement, perform a test. Start the engine. Finally, you should check the fuel pump, make sure the connections are tight and there are no leaks.

Pump operation

Anything can happen while operating a car. In particular, the fuel pump may break down. Or the fuel tank is dirty, and therefore the filter installed at the bottom of the pump. It is worth paying attention to the fact that VAZ cars are very popular in our country. There are a lot of spare parts for them; you can find them in any auto store. True, the quality of products is not always good. Sometimes you come across outright fakes on the market that cannot last even a few months. Of course, you can run into a low-quality spare part even if you purchase it for a foreign-made car. The service life of the VAZ 2110 pump is about 100 thousand km. If we take into account the fact that on average a motorist travels about 30 thousand kilometers per year, then in the time period the pump service life will be about three years. After this, it is necessary to replace the VAZ 2110 fuel pump.

Is it worth buying a non-new part?

No and no again! And here's the thing:

• Worn metal. The pump elements can simply be worn away and covered with a thin layer of rust. As soon as you bring such a pump to your eyes, small grooves on the motor rotor will immediately become visible. The product will not last long;
• Electrical condition. Again, we wrote above that conductors can fail at any time after contact with fuel. When buying used, you don’t know how much mileage you have left before the fuel pump breaks down;
• Repair issue. Mechanical pumps are occasionally repaired, while electrical repairs are possible, but hardly justified (you will have to cut the housing and then somehow put it in order after the repair). While the used one offered to you may look good, you can never be sure what's inside. Repaired pumps can also break down at any time.

We conclude: buy only a new part, the savings here are not justified.

Performance check

Checking its performance will help make sure that the fuel pump has failed. For this you will need:

• screwdriver with Phillips bit;
• a piece of gas-resistant hose (50–80 cm) with a clamp;
• key to 17;
• empty 2 liter plastic bottle;
• a piece of insulated wire;
• stopwatch.

Performance testing is carried out as follows:

1. We remove the back seat. We lift the carpet and find the gas tank hatch under it. Unscrew the two screws (diagonally).
2. Once you remove the hatch, you will see the top of the fuel module. Using a 17 wrench, unscrew the nut of the outlet fitting. We put a hose on it and secure the connection with a clamp. We lower the other end of the hose into an empty bottle.
3. Disconnect the pump power connector. Using a piece of wire, we supply power to the positive contact of the device from the corresponding battery terminal. We connect the negative one to ground.
4. We begin counting the time from the moment the pump starts.

A working fuel injection pump for a VAZ 2110/2112 should pump 1.5 liters of fuel in one minute. If this indicator is lower, the pump must be replaced.

A brief tour of brands

We recommend purchasing original OEM parts for your vehicle. You won’t have to choose for long, since you are buying a fuel pump specifically for your model. The market for originals is represented by some of the brands that we will list below. The difference is in labeling and approach to quality assessment. For example, at Mercedes-Benz factories, fuel pumps are tested several times additionally, so that only the best parts are sent to assemble the car.

If your finances are not very limited, pay attention to the following analogues: Pierburg, Bosch, Siemens (Germany). The products are cheaper than original parts, but are slightly inferior in quality.

Cheaper options: JP Group (Denmark), Meyle (Germany). It cannot be ruled out that they will last a little less than 200 thousand kilometers.

We advise you to take analogues of a high price category - it’s worth it.
