I decided to write about my replacement of the fuel pump with a more productive one from the Gazelle (everyone will laugh and say that it’s a collective farm, but this is a good replacement and tuning).
Our Fedors have a fuel pump with a capacity of up to 90 l/hour, after my pump died (at night) I installed it according to reports from the FF club from a VAZ 2110 No. 0 580 453 453
I didn’t see any difference with the original, but since I am still the owner of a gazelle car. Therefore, I know that in terms of the dimensions of these vehicles, the only differences are the same in performance and spare part number from the gazelle 120 l/h No. 0 580 454 001
and here is a photo of our dear b/n.
Good luck to everyone on the roads!
Added a photo with a cutting line.
FITS ONLY 1.8 AND 2.0; they have injectors with a capacity of 150 g/min. 1.6 has injectors with a capacity of 105 g/min.
| Sooner or later, the VAZ 2110 fuel pump becomes unusable, most often the brush assembly becomes unusable. There are many pump manufacturers, but do you know which one is better to choose a fuel pump for a VAZ of the tenth family? |
When choosing a fuel pump, we want the new part to fit the car perfectly, and also to be reliable and last for many years. Another important characteristic of a gas pump is “noise”; the quieter the pump is, the more comfortable the car will be.
About the interchangeability of fuel pumps. If you open the spare parts catalog, you can see a large number of catalog numbers of fuel pumps used on the “ten” with an engine capacity of 1.5 liters: 21102-1139009-02, 21102-1139009-03, 21102-1139009-06, 2112-1139007, 2112- 1139007-01, 2112-1139007-06, 2112-1139009-02, 2112-1139009-03, 2112-1139009-06. The difference is usually in the fuel level sensor (FLS), so when choosing a new fuel pump assembly, it is recommended to buy a part with a similar part number.
You can select a separate fuel pump with number 21101-1139009, which is used on cars with 1.6-liter engines and has a built-in fuel pressure regulator.
Stories from our readers
“Fucking basin. "
Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.
Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2. Practice on a Demo account (it’s free). 3. As soon as you get something on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY!

Electric type fuel pump
The fuel pump for VAZ 2110 is an electric injector and is installed in cars with an adjustable injection system. The “tens” electric fuel pump is located in the fuel pipeline system in the vehicle’s gas tank. This dislocation of the element greatly reduces the possibility of fuel loss due to the use of a scheme without the participation of pipelines that work to suck in fuel.
This element of the fuel supply system includes:
- EDH;
- a pump, the body of which is made of metal;
- fuel level sensor;
- fuel intake component;
- filter mesh;
- check valves and pressure reducing valves.
The valve of the reverse principle of action stops the fuel distribution complex when the power plant is stopped. A pressure-reducing element controls pressure by acting as a bypass valve.
The designs of electric fuel pumps are:
- roller type;
- gear type;
- centrifugal type.
An electric roller pump sucks in fuel and drives it through the functionality of the rotor element and the movement of special purpose rollers. The gear electric pump sucks in fuel and drives it through and is pumped by moving an internal gear relative to the stator element, which plays the role of an external gear. When a rotational type rotor moves, the side elements of the tooth create a chamber in their segments that changes the degree of rarefaction, with the help of which the effect of suction and supply of fuel is created.
At the same time, a centrifugal type fuel pump is mounted directly in the fuel line. Such elements make it possible to ensure an even supply of fuel and operate almost silently. They have one significant feature - a limit on pressure parameters and functionality.
Where is he located?
This device is located in the fuel line or in the fuel tank. Thanks to this placement, the risk of losses is significantly reduced due to the absence of suction lines.

The design of the electric pump assumes the presence of the following elements:
- Electric motor.
- Pump housed in a metal casing.
In other words, this device consists of an electric drive and a pump part. All its components are in direct contact with the fuel. In addition to the above elements, the module of this device also includes a fuel flow sensor, a fuel intake and a strainer.
And the part we are considering operates due to the presence of two valves - a check valve and a pressure reducer. The first locks the system when the engine stops operating. The second one performs the function of maintaining pressure in the system, while part of the fuel is transferred back to the inlet.
There are several types of electric pumps based on their design:
Selecting a pump for supplying fuel to a VAZ 2110
Despite the reliability of the element, the fuel pump sometimes becomes faulty. As a rule, the defect consists of failure of the electric pump brushes. The choice of a fuel pump is carried out according to the following criteria: reliability and quiet operation, because the quieter the pump operates, the more comfortable it is to use.
When choosing a fuel pump, you must purchase the same product with the same part number. Often, among many analogues, car enthusiasts highlight the Bosch fuel pump, which is used on 1.6-liter cars and is equipped with a fuel level pressure regulator.
Repair kit
A Bosch fuel pump repair kit consisting of rubber products will help you make repairs.
Everything described above shows that your desire alone is not enough for the fuel pump repair to be carried out efficiently. It also requires high professionalism of the craftsman and special equipment. This repair technique can only be implemented at equipped service stations. In addition, large stations have a large number of used parts that can be used. If these conditions are met, two-thirds of the total number of failed fuel pumps can be efficiently repaired.
Real life proves that after restoration, fuel pumps can work for quite a long time.
Diagnosis of the causes of malfunctions and replacement of the VAZ 2110 fuel pump
A fuel pump is essentially an electric motor that sits in a vehicle's fuel tank and pumps and delivers fuel to the injectors for injection into the combustion chamber at high pressure.
As a component and part of a car, the fuel pump is one of the important and finicky components of the car. With its help, fuel is supplied to the injector.
If used incorrectly, failure of this part can lead to consequences ranging from inoperability of the fuel system (especially during a long trip) to costly repairs of the entire engine power system.
Fuel pump VAZ 2110
Roller
This device sucks in gasoline and pumps it through the operation of the rotor and the movement of special rollers. When the space between these two parts increases, a vacuum is created. Thanks to this, the fuel fills all the empty space. When it is completely filled, the gasoline supply stops. As the rotor rotates, this space gradually decreases and at some point the inlet port opens. The fuel leaves the pump under pressure.
Causes of malfunction
The main causes of malfunctions of the VAZ 2110 fuel pump are the low quality of the fuel being filled, low fuel supply pressure, the regular presence of a small amount of gasoline (less than 5 liters) in the fuel tank and improper operation when starting the engine - before starting the engine, you must wait after turning on the ignition 2-4 seconds to pump fuel into the engine power system.
It is also possible that the fuel pump as a part will naturally fail, depending on the mileage of 150 - 200 thousand km. or for a period of 4-5 years, but again this malfunction depends on the operating conditions of the car itself.
Usually the factory fuel pump is replaced with a BOSCH one.
There are secondary malfunctions of the VAZ 2110 fuel pump failure - failure of the relay, blown power fuse, they are located in the fuse mounting block either under the hood or in the lower left part of the dashboard, front console, depending on the engine modification, and contamination of the fine filter mesh fuel cleaning (located directly on the fuel pump).
These faults can be fixed relatively quickly and without large financial investments. Fuel pump repairs are performed quite rarely, and the cost of repairs relative to the cost of the pump is insignificant.
How to check the pressure in the fuel rail yourself
Welcome, friends, to the DIY auto repair website. The task of the fuel system is high-quality, timely and complete supply of gasoline to the engine, as well as storage and purification of fuel.
Checking the fuel rail pressure
Structurally, the system consists of a fuel filter, injection system, fuel pump, tank and other elements connected by conductors.
In this case, the main function is performed by the fuel pump - it creates the necessary pressure in the fuel rail. If it decreases, serious malfunctions in engine operation are possible.
Symptoms of a problem
As a rule, checking the pressure in the fuel rail is required in the following cases:
- If malfunctions occur in the operation of the power unit at XX. In such a situation, the car may stall at the most unpredictable moment (even at a traffic light);
- the motor begins to stall, obvious instability appears in its operation;
- Significant excessive consumption of gasoline is noticeable. Consumption can generally increase by 30-50%;
- the volume of carbon monoxide in the exhaust increases.
Troubleshooting
The main symptoms of a malfunction of the VAZ 2110 fuel pump are engine interruptions in various operating modes, lack of pressure in the fuel system, loss of acceleration dynamics, increased fuel consumption, or complete failure when trying to start the engine.
The first step is to check the functionality of the pump. When you turn on the ignition, you should hear a slight whirring sound from the pump under the rear seat for a few seconds.
If the engine is running, it is necessary to check the fuel supply pressure using a pressure gauge; the fuel supply pressure to the injector should be 3.5 - 4 atmospheres. If the sound of the fuel pump is not heard, if you have an electrical tester, you can check whether power is being supplied to the pump.
To do this, you need to remove the back seat of the VAZ 2110, the decorative cover, and the terminal from the fuel pump housing, turn on the key to crank the starter, if the tester does not receive power, you need to check the relay, fuse or wiring trace for a break! If there is power, the fuel pump needs to be replaced.
The serviceability of the relay can be checked by replacing it with a working one from the fuse box, for example the high beam headlight relay. When replacing a new relay, you need to pay attention to the manufacturer and the recommendations of a spare parts specialist in the store; it is better not to save on the cost of the relay.
Replacing a fuel pump with a new one requires careful selection of the manufacturer; each pump has its own performance. The absolute leader in this area is BOSCH.
To replace or remove for repair the VAZ 2110 fuel pump we will need: a 17mm wrench, depending on the modification, a 10mm socket, pliers, a flat screwdriver. We remove the rear seat, it is advisable to unscrew the gas tank cap to relieve excess pressure in the system. Disconnect the plastic pump power terminal.
Depending on the modification, we remove the fuel supply and return hoses, or, by pressing the spring clip and pulling the hose, disconnect it from the fuel pump housing. In the second option, use a 17mm wrench to unscrew both fittings and disconnect the tubes.
In both cases, it is necessary to disconnect carefully, since the system is under pressure and when disconnected, the pressure will be released from the injector and a small amount of fuel will leak. If the performance of the old fuel pump is small, there will be no pressure in the system.
Unscrew the 8 nuts from the studs using a 10mm socket and remove the retaining ring with the seal. Carefully pull out the VAZ 2110 fuel pump housing at a slight angle so as not to damage the fuel level sensor; repairing it is unlikely. Using a screwdriver and pliers, remove the lower part of the fuel pump housing and remove the connectors and hoses from the pump. We dismantle the pump.
Installing a new
Installation of a new electric fuel pump is carried out in the reverse order.
The following actions are performed sequentially:
- The seal is installed.
- The new pump is carefully inserted.
- The pressure ring is installed and 8 fastening bolts are tightened.
- The fuel lines are screwed on.
- The power supply is connected to the connector.
- The hatch cover is installed and closed with the folded carpet flap.
- The rear seat cushion is installed.
- The battery terminals are connected.
When installing, remember that the arrow stamped on the housing must be directed backwards.
Characteristics of the Bosch VAZ 2110 fuel pump (pressure and performance)
The topic is open to those who are looking on the Internet for information about the technical characteristics of the Bosch fuel pump for the VAZ 2110. If you were looking for information about the fuel pumps for the VAZ 2110 Bosch, then this is an incorrect request.
Fuel pumps most often mean high-pressure fuel pumps, also known as injection pumps, and this is closer to diesel fuel systems. Gasoline engines have fuel pumps - mechanical and electric.
On the VAZ 2110, the Bosch electric fuel pump is probably the most popular fuel pump, because it has a relatively low price and universal dimensions, as well as availability in most stores.
Let's look at the following topics:
Fuel pump VAZ 2110 Bosch performance/pressure
Characteristics of Bosch fuel pumps and specifically the Bosch fuel pump 0580453453
How to buy a quality device?
The price for a VAZ 2110 fuel pump in market conditions will be 2 times lower than in a specialized store. The equipment is in durable and sealed packaging. Inside the package is purified gasoline. If you smell gasoline, then the seal of the packaging is broken and there is a possibility of corrosion forming inside the gasoline pump. Submerged equipment is lubricated and cooled by fuel. When using low-quality additives and gasoline, internal electrical mechanisms are corroded. If additional substances are not used in the operation of the device (dry), then the brushes wear off and it overheats. The service life of the equipment is longer. Some car owners are planning to replace the VAZ 2110 Bosch fuel pump, the characteristics and pressure of which are not normal only due to long-term use. Its pressure can be 6-7 atmospheres. It was amazing to hear from an experienced driver his method for testing the fuel pump. To do this, he took a jar of water, turned it on on the battery, and by the flow of liquid he realized that the power of the gas pump had decreased.
Bosch fuel pump performance - from 3 to 3.8 bar
The manufacturer Bosch produces its own fuel pump for each type of fuel system. Why, after the original fuel pump fails, do people install a Bosch fuel pump from a VAZ 2110? How does the pressure and performance of the fuel pump compare with the original one? If you put it with high pressure, will the flow rate increase?
Consumption does not increase due to the performance of the fuel pump, since on cars the return line is activated and excess fuel is returned to the tank, there is also a fuel pressure regulator, from the name it is clear, I think what function it performs.
Consequently, there was a 2.8 bar pump, they installed a Bosch VAZ 2110 fuel pump with 3.8 bar and it will only get better. Fuel consumption may increase if the fuel pump does not create sufficient pressure in the rail and the injectors begin to pour gasoline, which does not burn, rather than spray.
Centrifugal
Due to their design features, these two pumps are installed directly in the fuel line. Today's injection devices use centrifugal-type mechanisms. Such pumps provide a uniform supply of gasoline and practically do not make any noise. But they have their limitations in terms of pressure and performance.
The condition and serviceability of the fuel pump affects the stability of the engine, fuel consumption, and engine starting. It is important to constantly monitor his condition. The VAZ 2110 fuel pump module has a list of typical faults characteristic of parts of this type.
Characteristics of the Bosch fuel pump 0580453453
Especially for my readers, I got confused and measured the fuel pump that is on my display case. In fact, the characteristics of Bosch gasoline pumps differ in the length and very rarely in the diameter of the body. Why? The diameter of the body can be adjusted using a gasket made of petrol-resistant rubber.
Most often, the characteristics of fuel pumps (not only Bosch, but also from other manufacturers) may differ in length, pressure, location of terminal chips and that’s it :). The fuel pump mesh does not differ in seating, but it may differ in shape.
The chip for the terminal can be remade or supplied from the same VAZ. The length of the fuel pump is important, since its operation depends on this when the fuel level in the tank is low, and if it is in the module, then you need a match to install it.
- Bosch fuel pump 0580453453 - 105 mm
- Bosch fuel pump 0580453449 - 65 mm
- Bosch fuel pump 0580453465 - 90 mm
