Replacing the fuel filter on a Ford Focus 2

The functional purpose of a fuel filter on a car is to clean the fuel that flows through the main channel from the fuel tank to the injectors of the power unit.

Failure to promptly replace the filter on a car seriously shortens the service life of the engine, and may provoke the need for major repairs in the near future.

The fuel filter on the Focus must be changed at least every 45,000 km - otherwise unclean fuel will enter the internal combustion chambers. Popular filter models for the second Focus:

1602781 FORD submersible – 4,300 rubles;
CMAX 0310 submersible – 3,700 rubles;
775238 ERA – 2,300 rubles;
KR2222F KRAUF – 1,900 rub.

As an option for your car, you can find analogues of parts produced for Mazda or Toyota, having first checked the part numbers for compatibility.

Note! The Focus was equipped with many motors that required filters of different form factors and cleaning abilities. To avoid purchasing the wrong part, you need to select a fuel filter based on the VIN number of the vehicle. You can check the compatibility of parts with your car on the manufacturer’s official website.

How often to change the filter on a FF2 car?

Gasoline cars of the FF2 model have 2 types of trainers:

Thin / FTO.
Coarse/mesh.

Both elements are located inside the tank, next to the fuel pump and level sensor. The manufacturer recommends changing them every 120 thousand kilometers. If the Focus 2 has an external filter (depending on the modification of the car), the regulations require replacement at 60 thousand kilometers.

It is obvious that no one in Russia takes the regulatory deadline for replacing these elements seriously. In fact, their resource comes out much earlier. Especially if you poured low-quality gasoline with many impurities or the car had a high mileage. You can determine the wear of the cleaners much more accurately by measuring the pressure. It should not be less than 3.65 kgf/cm2.

The reason for the decrease in pressure may also be a malfunction of the regulator, located in the same module with filters or a pulsation compensator (located in the fuel rail).

On diesel FF2s, the trainer is located under the hood, behind the engine valve cover. The cleaning element is paper, the replacement period is once every 25 thousand kilometers.

The 2008 restyling did not affect the location of the filters; they are in the same places on the sports versions of the RS and RS500.

Replacing the fuel filter on a diesel Ford Focus: how it's done

On diesel engines, the fuel filter is very conveniently located, so even an inexperienced mechanic should not have any difficulties replacing components. To replace a part you must:

We find the fuel filter protective casing and unscrew the 2 fixing bolts, after which we carefully remove the shield on the casing;
Now carefully remove the fuel pipes from the filter. Remember, after disconnection, the remaining diesel fuel that was pumped from the tank into the fuel system will flow from the hoses;
Next, unscrew the fixing clamp on the filter itself and disassemble the part - you need to remove the old filter element.
Then fill the fuel system halfway with diesel fuel and install a new part. The system is assembled according to these instructions in reverse order.

Important to remember! Considering the quality of Russian diesel fuel, the fuel system filter must be changed a little ahead of schedule according to the regulations - once every 35-40,000 km.

Which fuel filter for Ford Focus 2 should I choose?

The second generation of Focuses were equipped with different types of fuel purifiers. Depends on several criteria:

volume of the power unit (1.4, 1.6, 1.8, 2.0 or 2.5 l);
engine type (diesel, gasoline);
Year of release.

The location of the filter element also depends on these parameters.

There are now many manufacturers of fuel filters for the Ford Focus 2, but the most famous is Mann.

Popular brands:

Ford Focus

For the second Focus with gasoline engines, FTO (fine cleaning) is selected according to the standard article number 1602781. This is a full-fledged module, inside of which is a gasoline pump, two components for delaying impurities and a fuel level sensor - the same pump is installed on the Ford C-max hatchback. As for the thin filter, it does not have a separate factory article number, but you can replace it with non-original products from companies so as not to buy an assembled module:

LYNXauto with article number LF−964M;
JS Asakashi FS 25004.

Both elements cost up to 1600 rubles.

The mesh or coarse cleaning element also does not have a separate article from the manufacturer, but if necessary, it can be replaced with Toyota’s 2321774021 for 300 rubles.

Filters on diesel versions are another matter. The FTO is taken outside and located in the engine compartment. It varies depending on the modification of the “engine”:

on 1.6-liter versions it comes with its own housing and hoses;
on 1.8- and 2-liter models it is a replaceable cartridge without a housing.

Trainers of 1.6-liter diesel modifications have different types of housings - plastic or metal. They differ in material, shape, and size.

Replacement methods

Therefore, there are only two options left:

Replace the entire unit at an authorized dealer.
Disassemble and clean the unit yourself.

Which path to choose is something everyone must decide for themselves. Of course, the first option will be expensive. Here you need to take into account both the cost of the work itself and the cost of filters (code B33063PR). But the fuel pump may also need to be replaced.

Disassembling a non-collapsible block

Let's figure it out little by little. But the manufacturer says that it is not collapsible!

The second option will be cheaper. Despite the fact that the manufacturer made the unit non-separable, domestic craftsmen found a way to disassemble it and change the mesh on the filters. No one will use this method at official stations, but the fact remains a fact. There is an opportunity.

We climb to the fuel filter.

If you also have experience or certain skills, then you can do this work yourself.

How to change the fuel filter: instructions

Let's first consider how to replace the element on gasoline Focus 2. If the thin filter is remote and located outside the tank, it is very easy to change it. It is enough to replace it in the engine compartment. If it is near the tank, you need to crawl under the car, which has been previously jacked up. You need to do this:

remove the pump fuse, shutting off the fuel supply;
turn on the engine - idling it until it stops spontaneously will allow you to relieve pressure;
Unscrew the filter fastening to the body (clamp);
pull out both fuel hoses by pressing the corresponding clips;
remove the old element;
install a new cleaner.

To replace the mesh and submersible fine filter, you will have to work hard. The manufacturer did not provide a special hatch, as on other cars. The factory method of removing the fuel module is complicated - you need to dismantle the tank. It is much easier to do this - find the wires going to the pump and cut the metal at this point. All that remains is to bend the sheet of iron, unscrew the fastening nut and pull the module out. The mesh can be replaced or immersed for 30 minutes to be cleaned in a solvent. At the final stage, be sure to blow out the mesh with compressed air.

Ford Focus Fan

Replacing the Ford Focus 2 fuel filter - diesel is more convenient due to the fact that it is located in the same place as the air filter. Well, we, the petrol ones, have to crawl under the car.

It is better to install any filters that are new and original. This applies to those who like to clean and put the clogged filter back... The cuff inside still won’t be cleaned

The fuel filter on the Ford Focus 2 (petrol) is installed in the rear of the car near the tank and is a fine filter with a paranitic gasket inside a sealed metal housing. This is an important element in cleaning gasoline or diesel. Its job is to prevent contaminants from entering the fuel pump, which could damage the fuel pump. By the way, gasoline for the Ford Focus 2, and for any foreign car, should only be filled at official and reliable gas stations.

When and after how long should you change the Ford Focus fuel filter?

The Ford Focus 2 fuel filter, as on the 1st and 3rd Focus models, is replaced every 30 thousand km. The frequency of replacing the air filter, as well as changing the cabin and fuel filters, is better to reduce with our quality of fuel.

Often, people ask questions: how to choose a fuel filter, which fuel filter to buy for a Ford Focus. It is better to take an original Ford fine filter from a German or American manufacturer Ford. After all, many components are produced in Germany. Fuel filter Ford Focus 2, the price is, on average, 1000 rubles. There is no need to skimp on quality, because the purity of gasoline will, to some extent, extend the life of the spark plugs.

For convenience, use a socket wrench or a ratchet with a head and extension

Just in case, I personally cleaned the throttle valve after the replacement so that the car could breathe even easier. Replacing a Ford Focus fuel filter with your own hands is as simple as replacing an air filter, but you need a lift or pit. We unscrew the bolt of the filter mounting bracket, after which it will be possible to lower it with the tubes below for ease of dismantling. Now you need to disconnect the fuel pipes. To do this, you need to pry the lock with a flat screwdriver and move it to the top position. Same thing on the second tube...

Make sure that the retainer is intact and does not break when removing...

After this, unscrew the bolt that tightens the bracket clamp, clamping the filter. We take out the filter. There is no need to clean the fuel filter and put it back. It won't work anyway... This is a one-time thing. We insert the new filter into the bracket and tighten the bolt.

There is an arrow on the gasoline filter indicating the movement of fuel from the tank to the fuel pump. Do not mix it up during installation, otherwise gasoline will not flow...

Now, first we connect the fuel pipes to the filter. We press in the clamps that we pryed with a screwdriver and lifted. Now, screw the bracket to the body. On most cars, the fine filter is changed in the same way. The main thing is to be careful when working, because gasoline leakage is inevitable. Don’t delay with the replacement, just like with changing the engine oil, the sooner the better...

Ford Focus fuel pump: manufacturers, location and reasons for failure

The fuel pump is the main component of the fuel supply system. Almost any malfunction leads to the engine stopping.

The first generations of Focus cars were equipped with standard fuel pumps. Since 2007, the manufacturer began to equip machines with devices with an emergency shutdown function. This function is activated at the moment of an accident and completely stops the supply of fuel to the system.

Manufacturers

New Ford Focus vehicles are equipped with Visteon fuel pumps. This is an American corporation that produces and supplies components for almost the entire family of Ford cars. Now Visteon representative offices also operate in Russia, so Focus car owners will always be able to purchase the necessary spare parts in the original version.

The body of the original fuel pump must have a yellow sticker from the manufacturer

For non-original components, it is recommended to buy fuel pumps manufactured by Mesmer and Era. They are quite reliable and cost much less than Visteon.

Location

Getting to the fuel pump in a Ford Focus is quite difficult. The manufacturer did not assume that Russian car owners would change it themselves, and installed a pump in the gas tank.

On a Ford Focus, the fuel pump is submerged in the gas tank.

Symptoms of malfunctions

You will most likely need to replace the fuel pump if:

when you press the accelerator pedal, the engine starts to run jerkily;
at idle speed the engine is unstable, with “dips”;
the car does not start the first time;
fuel consumption is significantly higher than usual.

A failed element cannot be restored, so you should not try to repair it.

When is a fuel pump replacement required on Focus 3?

Of the elements of the device, the filter most often fails. According to the manufacturer's regulations, it is designed for 30 thousand km. prb., however, taking into account Russian roads and fuel quality, this figure is reduced by about a third. A replacement can also be caused by the owner of the Focus 3 forgetting to refuel regularly, as well as by clogging of the device or problems with the electronics.

What does this lead to?

The fuel system makes strange noises, the pump itself hums.
The engine runs unevenly.
When accelerating at low speeds, it may stall.
There are “dips” at idle.
The engine power is noticeably reduced and the car moves jerkily.
Gasoline consumption is increasing.
The engine won't start at all.

USEFUL TO KNOW: Signs of a fuel pump malfunction usually manifest themselves in a complex manner. If, for example, the car does not start, this may indicate problems with the ignition system - starter, spark plugs, etc. You need to diagnose the pump to make sure it is in normal condition or needs replacement.

The process of removing the fuel pump

Using gentle pressure, release the fuel line and remove the electrical power connector.

We indicate the location of the fuel pump.

Using a grinder, we cut out an almost complete circle in a metal sheet.

We bend the resulting cover and gain access to the fuel pump, now it can be removed.

The fuel pump is held on the tank with a threaded cap. We rest a wooden stick against the stiffening rib of the lid and, tapping with a hammer, begin to rotate the lid counterclockwise.

When rotation becomes easy, unscrew the cap by hand and carefully remove the fuel pump.

On a free, flat surface (table, cart), having previously shaken out the remaining gasoline, we disassemble the fuel pump: Remove the cover from the latches and access to the filter opens.

You can see how dirty the filter is. We replace the filter with a new one and put everything back together. If there is no new filter, then we do it differently.

Carefully remove the filter and place it in the solvent for about twenty minutes, after which we vigorously shake it out or even knock it out, ensuring that all contaminants are completely removed. If the result is not satisfactory, repeat the procedure.
