Procedure for replacing the fuel filter in Ford Focus 1, 2 and 3

Author: Victor

The fuel filter in a car is responsible for cleaning the fuel coming from the tank to the injectors. The proper operation of the engine depends on this, so the car owner should regularly check the condition of the cleaning elements. For rules for selecting, installing and replacing a fuel filter for Ford Focus 3, 1 and 2, read the source.

Where is the fuel filter located?

First, let's consider the issue of installation and location of the element in the Ford Focus gasoline system, since before changing you need to know where the filter is located. On first generation models, in accordance with the diagram, the filter device is installed under the bottom of the car on the highway, in the rear of the car. In the second and third modifications of the Ford Focus, this element is installed in the fuel pump located in the gas tank. The difficulty of replacing the device in these cars is that the pump itself is non-separable. The fuel cleaning function is performed by a special mesh.

Filter mesh in the fuel pump

Ford Focus 3 100, 105 station wagon, hatchback, sedan, 2007 and other restyling and pre-restyling cars can be equipped with two fuel filters - coarse and fine. The former are used to filter out large contaminants that enter the gas tank with fuel, and the latter - from smaller components. In some American versions of the Ford Focus with a gasoline engine, coarse cleaning devices are mounted in the tank, and fine cleaning devices are mounted in the engine compartment, right in front of the injector. But often these components are placed under the rear passenger seat and are part of the same design as the pump.

Useful information and nuances of installing filters

It’s interesting, but original filters for Ford Focus are practically never found on sale. Thus, the manufacturer forces you to change the entire pump assembly. The Ford Focus car uses two types of filters: FGO (for coarse cleaning), which is a mesh, and FTO in the form of a flask.

The purpose of the filters does not need to be described in detail. Let's just say that they efficiently clean fuel in two stages. This practice has long been found in the automotive industry: one filter removes all large particles of debris (mesh), the other qualitatively cleans the fuel before it is directly supplied to the engine.

The coarse mesh on the Ford Focus is located inside the pump

Fuel filters on a Ford Focus can have different designs and be located in different places, depending on the modification and system of the car. For example, on injection internal combustion engines, the FTO remote filter is located near the tank, and the FGO mesh is located inside the fuel pump.

On a Ford Focus, the FGO mesh is considered a disposable, non-removable element, and according to factory instructions, it can only be replaced when assembled with a pump. The replacement schedule for FTO (external) is every 60,000 km, for FGO (submersible) – every 120,000 km.

The location of the FTO on diesel Ford Focus is interesting. It is located at the back of the engine; the filter element itself is made of paper. The replacement period for such a filter is correspondingly reduced to 25,000 km.

Replacing the remote filter is quite easy. You need to crawl under the car, which you have previously placed on a lift or pit. Before doing this, you should put on protective gloves and open the sash or window in the garage to allow benzene vapors to escape. To ensure fire safety, it is recommended to turn off all heating devices.

Next you need to act in the following sequence:

1. Pour some fuel into the tank, start the engine and wait until it turns off (the system runs out of fuel - the pressure is released).
2. The filter is attached to the body with a bolt, and you need to unscrew it.
3. Disconnect the fuel hoses going to the filter (prepare an empty container in advance into which the fuel remaining in the pipes will be poured).
4. The filter can then be removed by disconnecting it from the clamp.
5. Tighten the new FTO into the clamp.

It is extremely important not to forget to mark the tubes, hoses and fittings that we remove.

Replacement frequency

How often and at what mileage you need to change the TF depends on the type of device:

1. Filter elements installed in the engine compartment can operate according to the regulations specified in the instructions for up to 40 thousand kilometers. In fact, the service life of devices whose vehicles are fueled with domestic fuel ranges from 15 to 30 thousand kilometers.
2. Filters, which are part of the same design as the fuel pump, can operate, according to official data, up to 150 thousand km. In fact, this figure is 70-100 thousand kilometers.

Despite this, we recommend periodically checking the condition of the device. Filter performance diagnostics should be performed every 10-20 thousand km.

The following symptoms may indicate a malfunction:

• the power unit of the car began to work unevenly, “troubled”;
• the engine loses power, it needs more time to accelerate and increase speed;
• when driving at low speeds, when the driver presses on the gas, the engine begins to stall;
• in cars equipped with automatic transmissions, gears may shift incorrectly;
• Fuel consumption increases in some cases by four liters;
• There were problems starting the engine.

User Valentin Grebentsov talked about replacing the fuel pump assembly with a fuel pump.

Design and principle of operation

A fuel filter is a device without which the design of almost all modern cars is unthinkable. At its core, this unit is a purifier of fuel entering the engine, which significantly extends its service life. In addition, the presence of a fuel filter has a positive effect on the entire fuel supply system: from small fuel lines to the injector or carburetor.

Regardless of the configuration or year of manufacture, the Ford Focus 3 is equipped with two types of fuel filters:

• A coarse cleaning unit that screens out the largest fractions that enter the fuel tank. These impurities can be seen either with the naked eye or through a magnifying glass.
• A fine cleaning unit that cleans fuel from smaller components of unnatural origin.

Note! In some variations of the Ford Focus 3, the coarse fuel filter is located in the gas tank (or rather, in the gas pump), and the fine filter element is located directly in front of the injector. However, most often both filter elements are built into the design of the fuel pump and, when replaced, require the purchase of this entire part.

Note that over time, the cellular structure of both filters becomes “clogged” with more and more impurities, as a result of which the parts begin to perform their functions worse. It is how soon this occurs that determines when the fuel filters will have to be repaired. Considering the quality of fuel in our country, unfortunately for many, this moment comes after one year, or at best several years of constant operation of the car. And Ford Focus 3 was no exception in this regard.

Selecting a filter

Now let's talk about choosing filter devices. You can find both original products and analogues on sale. Naturally, the manufacturer recommends using original devices.

Original

In diesel versions of the Ford Focus, Ford TF 1352443 can be used. In gasoline versions, the situation is somewhat different, since such cars are equipped with two types of TF, both filters are part of a single design with the fuel pump.

Depending on the volume of the power unit, it can use two types of fuel pump:

• two-liter engines and EcoBoost internal combustion engines use an original device with article number 1754929;
• in units with a volume of 1.6 liters, pump 1754799 is used.

Analogs

The cost of original filters is always higher.

If you want to save money, then for a diesel engine you can purchase an analogue:

1. AD 101300013. The quality of such filters is much inferior to the original devices, but their cost is lower.
2. Bosch F026402007. The best option for those who are looking for a filter with a good ratio of cost and quality. Bosch products are comparable to the originals.
3. Mann PU7002x. A good analogue for American-made cars.

In gasoline cars, non-original TFs can also be used:

1. Doda 1120020005. Designed for 1.6 liter engines. The design corresponds to the original pump and has a long service life. The main advantage is cost.
2. Era 775433 for the 1.6-liter unit and 775489 for the two-liter engine. In terms of technical characteristics, these analogues are practically not inferior to the original.
3. Bosch 0580200064 for 2 liter internal combustion engine and EcoBost. They are characterized by high quality and service life.

You can learn more about replacing the TF yourself from the video filmed by the AvtoVit Car Repair channel.

What fuel pumps are installed on the Ford Focus: models, design, location

In the fuel supply system of Ford Focus cars, the fuel pump plays the role of transporting fuel from the tank to the engine. It is advisable to install original spare parts on these cars. But they are expensive. Therefore, some are content with alternative options. For example, Italian ERA gasoline pumps are quite popular.

A few interesting points about Erov’s models:

• ERA is not a manufacturer, but a supplier of spare parts. It does not produce anything itself, but is only a packager of certain components. Thus, a fuel pump for an American car packaged by this company can also be considered an original part;
• Often on the market you can find fuel pumps packaged in the same boxes with the Mesmer inscription.
  The price of the models is almost half that of ERA products. What's the catch? It turns out that this is a “left-handed” pump, most likely made in China; It is recommended to carefully check the Messmer fuel pump in the package
• To identify a fake, it is recommended to look first at the label of the packaging box.
  The “Chinese” sticker is of lower quality, printed on a black and white printer. Secondly, look for the presence of a protective film on top of the pump, on which the ERA brand name should be applied. As a rule, it is not present on fakes; The ERA inscription inside the packaging indicates the originality of the product
• the presence of the Visteon label on the top of the pump can also be considered a signature feature of a real Ford product;
  Visteon label on the fuel pump as a sign of quality and originality

Similar fuel pumps that fit the Ford Focus without any problems are from the Volvo S40, Mazda 3. They cost a little more than the Italian ones, but are cheaper than the original ones.

In terms of design, the original fuel pump of Ford Focus cars is a model of an electric submersible rotary pump. The pump is equipped with coarse and fine filters and a pressure regulator. The submersible version of the pump model is considered the best today, as it reduces the risk of vapor locks. Fuel here is supplied under pressure, and not as a result of vacuum.

Original fuel pumps for Ford Focus are made in the USA. The price for parts is about 3–5 thousand rubles. (in times of shortage the cost jumped to 20 thousand rubles). Analogs, as mentioned, are almost half the price.

Ford Focus fuel pumps can be identified by catalog numbers:

• 1234552;
• 1254193;
• 1305354;
• 1309160;
• 1312617;
• 1529595.

There is no particular difference between fuel pumps for Ford Focus cars of different generations. However, it is recommended to indicate the year of manufacture and engine modification when purchasing.

The fuel pump is located on the top surface of the tank, next to the hatch. You need to remove the rear seat to get to it (on sedans) or climb from the trunk side (in hatchbacks). However, when developing the car, the engineers did not take into account that the pumps, although original (of high quality), are not at all eternal. If they had provided a hatch under the seat, dismantling the pump would have been much easier. Here the pump is placed directly into the tank. To remove it, you have to cut the tank.

Removing the fuel pump from Ford Focus cars is fraught with significant difficulties

The process of replacing the fuel filter in Ford Focus 1

Let's look at the detailed instructions for replacing the first versions of Focus.

Tools

To complete the task you will need:

• a set of wrenches - you will need tools for 7 and 8;
• knob with extension;
• the filter itself;
• rags.

Algorithm of actions

The procedure for repairing and replacing TF on the first version of Focus is performed as follows:

1. The car is driven into a garage with a pit or onto an overpass.
2. The pressure in the fuel line is relieved. To do this, you need to open the engine compartment and find a block with safety devices. The element responsible for the operation of the pumping device is removed and tongs are used for dismantling.
3. The ignition is turned on and the power unit is started. After starting, the engine will run for a few seconds until it stalls. This indicates a release of pressure. Try turning the starter again, the engine should not start.
4. The filter device is located in a special niche nearby, in the area of ​​the fuel tank. Climb under the bottom and you will see a filter located at the rear of the machine on the right.
5. Two lines are connected to the device. We leave the green one, since it ensures the return supply of fuel to the tank, and disconnect the second pipe. If there are contaminants on the line, they must be removed. When disconnecting, be careful as some fuel will come out of the filter device and pipes.
6. Using a size 8 wrench, you need to unscrew the screw that secures the TF to the car body. Remove the device with the mount. To disconnect the fastening element, loosen the bolt with a 7mm wrench.
7. Replace the new TF. The assembly process is performed in reverse order. Reconnect the fuel lines and secure them securely. When you hear a click when connecting, you can assume that the pipes are connected correctly. Reinstall the safety element and start the engine. There may be some difficulty starting it, but eventually it will start normally. A photo report on the replacement is given below.

1. Remove the fuse responsible for the fuel pump from the block

2. Disconnect the line from the filter device under the bottom

3. Install a new element and connect the lines to it

Replacement on a non-restyling car

Replacing the Focus before restyling is much easier. The entire operation takes no more than half an hour.

The recommendations for fuel exhaustion and pressure relief given above also apply to this model.

Tools and consumables

Filter without packaging

• Filter - catalog number FG 986 B.
• Key head with a long knob for 8 (handle length is desirable more than 15 cm).
• Key for 7.
• Rags for wiping.

Changing the filter on Ford Focus 2 and 3

Let's look at the process of replacing devices on the second and third versions of Focus.

What to prepare?

To change you will need:

• two screwdrivers - with a Phillips and a flat tip;
• set of wrenches;
• rags;
• new TF.

Stages of work

The change is carried out as follows:

1. Open the hood and remove the fuse responsible for the operation of the fuel pump from its seat. Relieve the pressure by starting the engine and waiting until it stops.
2. If you need to replace two fuel filters - under the hood and in the tank, then open the engine compartment and find the filter. It is located near the cylinder head. You just need to disconnect the line connected to it and remove the device, then install a new filter and securely connect the pipe to it. Make sure that the hose is securely connected to the device to avoid possible leaks.
3. As for the additional filter element, here the car owner may encounter a problem. The fact is that in the body under the rear seat in some versions of the Focus there may be no hatch that will allow access to the installation site. Therefore, the manufacturer recommends changing the device yourself by removing the fuel tank. To avoid removal, you can make a hole yourself, but keep in mind that this is unsafe. Some craftsmen make a hole using a grinder, scissors, or drill it, but we recommend dismantling the tank.
4. When you gain access to the pumping device, unscrew the ring that secures it using a screwdriver. Dismantle the pump, having first disconnected all wires and connectors, as well as lines connected to it.
5. Disconnect the connector from the level sensor in the pump and remove the controller.
6. This will give you access to the filter mesh. You need to dismantle it and install a new one. Further assembly is performed in reverse order. Many car owners, when changing the filter element, also change the fuel pump motor, if necessary.

The Artem&Marya channel published a video showing the process of replacing the filter and rear shock absorbers in a Focus 2 car.

Difficulties of replacement - what tricks should you be prepared for?

The main fuel filter system in the Ford Focus 2 is designed in such a way that replacing it is quite problematic. This car model does not provide for replacing the filter through the hatch under the rear seat, as in other car models of domestic and foreign production. Therefore, many drivers prefer to replace the filter at a specialized car service center.

However, despite the difficulties, you can replace this part with your own hands if necessary. To replace or repair the fuel pump and filter, the entire tank must be removed. Before replacing the fuel filter, you must first relieve the pressure in the fuel pipe system. To do this, you need to remove the fuse responsible for the operation of the pump from the car’s mounting block.

In Ford Focus 2, this is usually the 10th or 12th number, it all depends on the configuration of the car. After removing the fuse, start the car and wait until it stalls on its own. By this action we turn off the pump, and the fuel that is in the tubes is completely consumed. There will be no inconvenience when dismantling the tank. It is best to replace the fuel filter when there is a small amount of gasoline in the tank.

To remove the tank and further replace the filter, you must go to the inspection hole or perform this work on a lift. Before performing work, prepare a standard set of tools, as well as a new filter. It is worth noting that the filter for the second Ford Focus is not always available in the auto store. Therefore, you can replace it with a filter from a Toyota car - they are almost the same in size.

First of all, we need to unscrew the fastenings of the exhaust pipe and move it to the side so that it does not interfere with us in the future. After this, unscrew the fuel pipes, as well as the fuel supply hose from the tank cap. Carefully disconnect the power supply, the wires from which go to the tank to operate the pump. After this, unscrew the fasteners and remove the tank. It consists of two parts, so unscrew the bolts along its contour, then remove the upper part.

Now you can start replacing the filter, which is located in a plastic flask along with the pump. Be especially careful with the wires that go to the pump, as well as with the float sensor, which indicates the correct fuel level in the tank. After replacing the filter, install everything in reverse order. First, the tank body at the junction must be treated with a sealant and, if necessary, its gasket must be replaced to prevent gasoline leakage in the future.

Putting the tank back is much more difficult. To install it, prepare a jack or telescopic stand, depending on whether you are working on a viewing hole or on a lift. Without the help of these tools, it will be very difficult to position the tank correctly. After the tank is exposed, if possible, fill the tank to half its level and see if there are any gasoline stains on the joints. If any are found, tighten the connecting bolts.

The fuel filter performs an important function in any car, as it keeps the fuel and injector system clean for a long time. In addition, fuel purification significantly reduces the risk of damage to internal engine components due to poor-quality air-fuel mixture.

The Ford Focus 2 fuel filter has a standard device, but is inconvenient for maintenance and replacement. This is especially true for the coarse filter located on the fuel pump in the gas tank. Its task is to clean gasoline from large particles. The second filter in the engine compartment serves to finely purify the fuel before entering the injectors and directly into the combustion chambers of the cylinders. The use of contaminated filter elements is detrimental to the operation of the engine and the fuel system as a whole.

Replacement of TF in FF2 diesel modification

The procedure for changing the filter in diesel cars is slightly different.

What will you need?

To complete the task, prepare the following:

• the filter itself, original or analogue;
• one liter of diesel fuel;
• the cut-off bottom of the bottle to collect fuel that will spill out when removed;
• 8mm socket wrench.

Algorithm of actions

You need to remove and change the filter in diesel cars like this:

1. The device itself is located in the engine compartment, to the right of the power unit. The filter is hidden by a protective cover, secured with screws that are unscrewed with a size 8 wrench.
2. After dismantling, you will see the filter element, which has a special fitting. It is used to drain diesel fuel. Unscrew the fitting and place a container under it; some of the fuel will drain into it.
3. Remove the fuel filter cover and wipe the device with a rag to remove dirt to prevent it from getting into the pipes. Afterwards the cover must be disconnected.
4. Take a new TF and install it into the case. After installation, fill it with fuel. Make sure that the fuel has filled the entire space.
5. All components are assembled in the reverse order; do not forget to tighten the fitting.
6. Start the power unit and increase its speed to about two thousand per minute. In this position, let the engine run for a while, this will remove any air pockets from the fuel system.

Where to look?

In second and third generation Ford Focus cars, the fuel filter is located in the gas tank, inside the fuel module housing.
It is combined with a fuel pump. If the filter fails, the entire module is replaced. But domestic car enthusiasts found a way out of this situation. And indeed, it is not entirely correct to throw away a working unit just because part of it has worn out. Moreover, this part does not even perform any mechanical functions.

You should, of course, pay attention to the fact that the manufacturer strongly does not recommend any artisanal improvements to the part. Ford Focus 3 owners carry out all operations performed solely at their own peril and risk. However, since the "invented" method is of at least research interest, it is appropriate to share it here

In addition, the process of replacing the entire assembly is no different

However, since the "invented" method is at least of research interest, it is appropriate to share it here. In addition, the process of replacing the entire assembly is no different.

The procedure for changing the oil in a Ford Focus 3 engine

So, the idea is to replace the mesh filter in the fuel module with an analogue one, since finding an original part for the Ford Focus 3 will be problematic. As a rule, a mesh from Toyota is installed.

Alternative, but no less artisanal, methods of improving the fuel cleaning process are installing an additional (auxiliary) cleaning element in the fuel system, or installing a mesh from a used fuel pump. Both methods have significant drawbacks. For the first, this is an increase in resistance in the fuel system when creating the necessary pressure, which can lead to a decrease in the service life of the fuel pump. For the second, the purity of the purifier is questionable. That is, any of them can endanger the entire fuel supply system, as well as threaten the safety of the engine of your Ford Focus 3.

Replacing the fuel pump grid for Ford Focus 3

The first outpost on the path of microscopic debris rushing into the fuel system is the fuel pump mesh. If there is a risk of refueling your car with bad gasoline, it can save you from many major problems. So this detail should not be underestimated.

FOR REFERENCE: Sometimes it is not necessary to replace the entire pump when the engine is starved of fuel - just changing its grid is enough.

The technician will suggest replacing or cleaning this element, depending on its condition. The price difference between these options can be called symbolic.

The replacement option is:

• the fuel pump is removed;
• the body is thoroughly cleaned of traces of fuel (this is a mandatory safety step!);
• by unfastening the clamp, the float is obtained;
• wires and sensors are disconnected;
• the clamps in the pump are removed and the mesh is removed;
• a new part is installed in place of the old one;
• assembly - in the reverse order: clamping the clamps, connecting sensors and wires, installing the float, installing the fuel pump.

You can clean and install the part back when it has no damage - dents, peeling of the braid, etc. The mesh is removed in the same way as when replacing it.

Next is done:

• soaking the part in the reagent;
• cleaning with cleaner;
• blowing with a high pressure compressor.
