How to understand that the fuel pump has failed?
There are a number of signs that allow you to determine that the fuel pump has failed and began to work incorrectly (or has stopped working altogether).
How to disassemble the fuel pump of a Ford Focus 3?
The process of disassembling a fuel pump is a rather complicated procedure, since the fuel pump itself is a difficult element to disassemble; spare parts for it cannot be found on sale (for example, a pressure regulator, an electric pump), so if the fuel pump is damaged, it is usually replaced.
Replacing the fuel pump on Focus 3
Let's look at the process of replacing a fuel pump on a Ford Focus 3 using the example of a car equipped with a 1.6 liter gasoline engine (Duratec Ti-VCT engine). Before purchasing a new pump and directly replacing the pump, it is recommended to check the pressure in the fuel system of the machine. It must be at least 365 kPa, otherwise the fuel pump will have to be replaced.
How to remove the fuel pump on a Ford Focus 3?
To remove the Ford Focus 3 fuel pump, you need to prepare a hammer, a wooden drift and a container into which you can drain the fuel.
Fuel pump removal process:
- Remove the fuel tank from the car (the process is described in detail in the article on replacing the fuel pump on Focus 1)
- Next, you need to loosen the fastening of the fuel pump housing to the fuel tank - to do this, turn the ring counterclockwise, carefully hitting it with a hammer through a drift
- Afterwards you can unscrew the ring from the neck of the gas tank and remove the fuel pump
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 at least of research interest, it is appropriate to share it here. In addition, the process of replacing the entire assembly is no different.
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.
Ford Focus 3 fuel pump replacement
The Ford Focus 3 fuel pump should be replaced if it becomes noticeable that the fuel pump is not working as efficiently as before, or is not working at all. In the Focus 3, the fuel pump is a submersible pump; during operation it is cooled by the gasoline in which its body is immersed.
If there is not enough fuel, the pump does not cool down and overheating may occur - as a result, the pump will malfunction and may quickly fail.
Let's look at the main symptoms of a malfunction, as well as the processes of removing the fuel pump and replacing it on a Ford Focus 3.
Signs of malfunction:
- Noises are heard in the fuel system while the fuel pump is operating.
- The Ford Focus 3 fuel pump hums while the engine is running.
- Increased fuel consumption at the same level of consumption
- The car just won't start
The latter may be associated not only with problems in the fuel system, but also with malfunction of spark plugs, high-voltage wires, starter, battery and other system elements.
Why change?
If you do not systematically replace parts, the owner of a Ford Focus 3 may encounter the following problems:
- uneven operation of the motor (“troits”);
- loss of power;
- the engine stalls at low speeds when the gas pedal is pressed;
- in cars with automatic transmission, speeds do not switch incorrectly;
- increase in fuel consumption.
- All these manifestations may indicate that the fuel filter of your Ford Focus 3 is not doing its job, is not cleaning well or is leaking fuel.

And then we see that in order to remove the motor, you need to remove the insides (motor with filter) from the flask, and unfortunately they sit there on three pins to which they are glued. I tried to disassemble it carefully and didn’t know about the glue - I used a punch to knock on the center of the fastening to knock out the bulb pin. The result is that one pin broke, one burst, and one survived. I was afraid to put it all back, because... The car is not mine, and the motor with the filter in the flask is held on only by these pins - either glue it or put it through the bolts (also an option, just came to mind). I did it simpler - I found a working pump with a torn nipple on the top cover, and moved the cover from the non-working pump to the working one using soldering and corrugations from a Lada car.

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:
- 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).
- The filter is attached to the body with a bolt, and you need to unscrew it.
- 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).
- The filter can then be removed by disconnecting it from the clamp.
- Tighten the new FTO into the clamp.

It is extremely important not to forget to mark the tubes, hoses and fittings that we remove.
The Ford Focus remote filter is located separately from the pump
When installing a new filter, you should pay attention to the arrow marked on the housing. It indicates which side of the filter element should face the engine (that is, the filter should be placed so that it is directed with the arrow towards the car engine).
The arrow on the filter should point towards the engine during installation.
Replacement of the mesh is carried out together with replacement of the pump. However, there are motorists who know how to clean the mesh without changing it. There is another option: install a mesh from another car model at the inlet of the original fuel pump, thereby creating additional filtration. This is something like an upgrade designed to improve the stability of the engine for some time. In fact, only a full replacement of the element will make it possible to improve the dynamic and technical performance of the engine if the submersible filter no longer copes with its duties.
Almost all Ford Focus have a hole cut on top of the fuel tank, which is provided for removing the pump and filter without dismantling the entire tank.
The replacement algorithm looks like this:
- The rear sofa reclines.
- The wires going to the pump determine its location.
Wires to the fuel pump will help determine its location - If the hatch is not provided by the manufacturer, then you should use metal scissors to cut and bend the iron just enough so that it is enough to remove the pump.
A hatch cut out with scissors will provide easy access to the pump. - The pump is held on by a nut that must be unscrewed.

After the pump is dismantled, you need to remove the bottom plastic cover protecting the mesh.
The submersible filter is located inside the pump, it is hidden by the bottom plastic cover
All that remains is to remove the submersible filter and replace it. If the pump is being replaced, then you need to install a new unit in place of the old one. After assembly, be sure to pump some fuel into the system with the starter, but do not start the engine. Then you should check the connection for leaks. The car must also be tested in motion. If there are no leaks anywhere, all hoses and tubes are properly secured, then you need to drive the car at speed along the highway, then downhill. This is how the fuel supply is checked in different driving modes.
Some owners take old fuel pumps to car repair shops, where the units are repaired and put up for sale. If you don’t want to throw away the part, then you can do just that and make some money.

And so let's go. We lift the rear seat, we don’t see the hatch, no problem, using metal scissors we carefully cut out the hatch on the right side of the car, where the wires go. Remove the rubber plug that is on the wires and everything will be visible how and where to cut. I cut with metal scissors, guys, no grinder! You understand this is gasoline! You need to cut a circle with a diameter 2-3 cm larger than the fuel pump housing. There are no photos, but I think making a hole is not a problem, yes, and there are plenty of photos on the Internet. We unscrew the plastic washer counterclockwise (there was no puller; I unscrewed it using a hammer and a dull minus screwdriver, WITHOUT FANATISM, slowly). Yes, before unscrewing the washer, my advice is to dry clean everything with a brush and blow it with air so that dirt does not get into the tank. We get the pump. We remove the top cover, there are two guide pins, one of them has a stopper, be careful with it, I lost mine, it flew off when I removed it, fortunately I work in the service department, I found a similar one. The plastic gas hose was removed from the bottom of the pump using a blow gun. In the photo there is already a Priora pump, but this does not change the meaning. The pump with the filter housing is soldered to the flask at three points; the photo shows already drilled holes. We drill from the back of the pump with 3ka, then 5ka drills. The inside should come out, if it doesn’t, it means they didn’t drill enough. Do not pull or pick, you will break the flask. Photo 2 wires are soldered to the pump (in the photo the pump has already been removed, it is held by a mesh. The filter is on the latches, you’ll figure it out, there’s nothing complicated), we bite off the wires and take out the pump (do not lose the o-ring on the pump nipple), having previously marked the polarity. This is where the most important thing to do is to cut the bottom of the filter housing in a circle. It definitely needs to be pulled out, photo-3 it’s clogged! Simply replacing the pump won't do anything! Then the bottom needs to be soldered TIGHTLY, otherwise the pump will pump from tank to tank. And we need the entire filter housing because of the overpressure valve, located on top. Photo-4 are the three points where the internals are soldered. Move on to the pump motor, it needs a little modification. The fuel supply nipple must be shortened by about 5mm photo-6. otherwise the pump will not sit in its place. A valve will fly out, blow there, blow from there... well, you understand me, most pumps don’t have it, and without it everything works. Now saw off the bottom of photo-7 the mesh filter stopper, it will interfere because Our filter mesh will be positioned at 180 degrees. vice versa. Filter mesh, saw off the landing to zero photo-8. Yes, the filter mesh is triangular, you can see it in the photo. We put the filter mesh on the pump, insert the pump into the housing, there is no need to attach it in any way, it will rest against the flask with the filter mesh and will not go anywhere. In photo 9 the original pump is in the background. There is some kind of valve at the bottom of the flask, I didn’t bother wondering what it’s for, but if it’s there, it means it’s needed. Priora the pump is a little higher, so the tube from the filter housing does not reach it, it’s solved, photo-10. cut a piece from the Priora fuel pump pipe (sold separately at any auto store) about 2cm, heat it with a lighter and quickly put it on 1cm photo-11,12. We fasten the entire interior with bolts and nuts m-5 photo-13,14,15,16. I secured it with 2 bolts, I think it’s enough. Now the top. Everything is simple here, you need to solder the plug from the Priora pump. Everything is described in more detail in the blog. I edited the text and added photos.

Focus 3 fuel pump
Important points
- When unscrewing the fuel lines from the pump, you must be extremely careful and under no circumstances point the tubes at your face or towards the front seats, since the gasoline in them is under pressure. It is best to unscrew the tubes after wrapping the couplings with a rag.
- Since after all the above operations a round hole appears in the floor of the cabin, it must be repaired. For this, a square metal plate (dimensions: 30 by 30 cm) is suitable, in the corners of which holes are drilled. The floor in the cabin is thin, so the plate is easily attached to 4 self-tapping screws. This will reliably protect the pump from damage.
- To make it easier to cut through the floor panel with scissors, you can pre-drill a series of holes where the cut will be made. This can be done with a regular electric drill. However, the drill should not be too long, since in this case there is a risk of hitting the gas tank (and it is very easy to damage it, since it is plastic on the Ford Focus 2).
Of course, the method of replacing the pump given in this article can hardly be called beautiful. But it has three undoubted advantages. Firstly, it’s fast, and secondly, it’s simple, so even a novice car enthusiast can complete this task. And finally, it’s cheap, because you won’t have to pay auto mechanics at the service center to completely remove the gas tank and a lot of related operations.
How to open a key, disassemble the key fob and replace it
The side buttons on the Ford Focus 3 key fob are pressed
A screwdriver is placed between the halves of the key fob
- The edge of the plastic card is inserted into the resulting gap. The card moves between the halves of the key fob, along its entire perimeter, so the plastic latches holding the halves together open (there are 3 of these latches, 4.5 are located near the side buttons, another one is located at the end of the key fob).
- The halves open and the old battery is removed from the socket (for this purpose you will have to pry it off with a screwdriver).
- A new battery is installed in its place, then the halves of the key fob are placed on top of each other and snapped into place. The same is done with the outer cover: the side buttons are recessed into the key fob, the cover is placed there, then the buttons are released, reliably fixing this part of the analog key.

Smart Ford
Ford Focus 3, of course, can safely be called a “smart” car. The car’s electronics perform a huge number of functions, control the operation of the engine, diagnose the operation of various systems and components of the car and keep a huge number of all sorts of little things under control; from time to time the driver is reminded of this fact.
At first, there are no teeth to such little things, including monitoring the battery charge in the ignition key of the Ford Focus 3. This little thing is essentially of great importance. A huge number of drivers, whose cars are equipped with electric keys or alarms, at some point are faced with a situation when the battery from which the key or other key fob is required to operate is discharged. In this option, you either have to urgently find a battery or a spare key fob. Otherwise it is impossible to open and start the car. In this context, a timely reminder to replace the battery does not seem like a trifle.
Ford Focus 3, when it detects a weakening of the battery charge, from which the key is required, very aggressively reminds that it needs to be changed. Otherwise, the car simply does not move.

It feels like he's a dealer or a taxi driver. I bought the cheapest pump to remove the good original one and put it on my Ford, or to sell it. It's just so barbaric to do this to your car.
The main thing is that the comments are coming and the video is moving forward)))
Yesss! Friends to such a surgeon, God forbid.
Easier said than done! and I do not pretend to repair your car)
After making the hole, now the passenger’s ass will always be covered in dirt, it’s absolutely brutal!
