The fuel pump and filter are one of the main elements of the fuel circuit. They are entrusted with the task of uninterrupted supply of fuel to the main line. Their failure can lead to complete immobilization of the vehicle. Therefore, the fuel filter and pump must be replaced at the first symptoms of their breakdown.
The original Toyota Corolla 120 fuel pump has article number 2322128030. Its price is more than 2,500 rubles. There are analogues from third-party manufacturers. Their best options are shown in the table below.

Frequency of replacing the fuel filter
The automaker produces the Corolla 120, which is equipped with fuel filters designed for the entire service life of the car. In domestic realities, the quality of gasoline is extremely low, which causes the filter to clog and the fuel pump to fail. Therefore, official dealers recommend replacing the fuel module every 80 thousand km.
In most cases, there are no obvious symptoms of a clogged fuel filter. This is due to the fact that throughput decreases gradually throughout the entire life of the vehicle. In this case, a clogged filter element can have a negative impact on the power plant and its associated components.
The design of the fuel filter and its necessity
The filter element is designed to provide the cleanest fuel possible for smooth engine operation.
There are 2 main types:
- submersible, which is installed inside the fuel tank;
- external, most often located under the hood or bottom of the car.
Both elements must be replaced.
In most cases, the fuel filter consists of a single module, which includes elements of coarse (FGO) and fine (FTO) cleaning.
The first is a metal cylinder with a fine mesh that does not allow contaminants larger than 0.1 mm to pass through.
The second is a plastic housing with paper inserts inserted into it, ensuring complete purification of the fuel from the smallest particles and impurities.
However, on Toyota Corolla cars, these elements are divided into 2 independent modules, which are located in different places. The coarse filter (submersible) is placed at the inlet of the fuel pump in the gas tank, and the clean filter (external) is placed on the main line. There are different models installed on the machines.
Installation depends on the year of manufacture and body size (120, hatchback or 150). However, the principles of their replacement are similar, differ in minor details, and allow you to do the work yourself.
Required Tools
In order to successfully replace the fuel filter on your Corolla 120, you will need the tools from the table below. Table - Tools required to replace the fuel filter.
| List of tools | Note |
| Screwdriver | With flat and cross blades |
| Vacuum cleaner | To clean dirt |
| Capacity | To drain remaining fuel |
| Pliers | Can be replaced with pliers |
| Technical hair dryer | Required for vehicles in which the service hatch is secured with bitumen |
| Brush | To reduce the risk of contaminants and foreign particles entering the gas tank |
Frequency of replacing the fuel filter on a Toyota Corolla
According to the operating instructions, the fuel filter must be replaced every 80 thousand km. Many car owners drive without changing the filter, thereby almost doubling the recommended mileage.
You can’t treat the fuel system and engine this way, because it’s no secret that the quality of domestic gasoline is much inferior to the Japanese standard. Therefore, keep in mind that the fuel filter, like any other cleaning element, cannot last forever and its resource is limited by the mileage of the car or a certain time interval. Maintenance specialists strongly recommend replacing every 50 thousand.
km run. However, replacing the fuel filter may be required earlier. Certain signs will indicate this to you.
Signs of a clogged fuel filter
Many Toyota Corolla car owners start replacing the filter only when there are clear signs of a decrease in the throughput of the cleaning element or when the engine fails completely. Since filter clogging occurs at a slow pace, it is not immediately possible to notice the obvious symptoms of its poor performance. And further operation with a clogged filter has a negative impact on the engine’s turnaround time, which is reduced.
Here are the main signs of a clogged filter:
- Uneven engine operation both at idle and under load
- Slow acceleration
- Unstable engine starting
- Unexpected engine stalls
Types of fuel filters for Toyota Corolla on the Russian automobile market Many auto stores offer a choice of at least three types of products of this type for Toyota Corolla. First of all, these are products from Chinese and Korean manufacturers, as well as the original version. Many motorists do not consider that the quality of filters of different types varies greatly. The main thing is that when replacing the filter, correctly install the sealing gaskets that come with them.
Depending on the modification of the Toyota Corolla car body and the year of manufacture (before 2007 or after), you should individually select a fuel filter that is suitable for the design. There are designs for fuel supply units from the gas tank, where the filter is located in the pump itself, so replacement has to be carried out as a whole module. The procedure is expensive, but the car owner still has no choice. Unlike these Toyota models, Corolla cars produced in 2008 were equipped with different designs of fuel filters, which can be replaced and installed separately from the fuel pump.
A rich assortment of foreign spare parts allows the car enthusiast to make his choice on a line, on one side of which is the cost of the product, on the other - the high quality standard of replacement parts. For example, the price for individual copies exceeds about 10,000 rubles. This is especially true for original products made from non-separable filter and pump units.
So, before replacing the fuel filter, be sure to familiarize yourself with fire safety precautions, and also stock up on the necessary tools and spare parts.
Replacing the fuel system filter on Corolla 120, 150
A car fuel filter is an important element that is used to clean gasoline or diesel fuel from foreign impurities and condensate, helping to extend the life of the engine and related systems. The filter on a Toyota Corolla requires replacement due to both natural wear and premature clogging, and it is important for the motorist not only to carry out the procedure itself correctly, but also to choose the appropriate spare part. This part has its own characteristics depending on the year of manufacture of the car and the type of body: for example, filters for Corolla 120 and 150 have a different design. Despite this, the replacement process does not differ significantly.
Fire safety during work
When working with the fuel system, compliance with fire safety regulations is a necessary requirement. The penetration of gasoline vapors begins within a few seconds after removing the gas tank cap. The mixture of air and fuel is very explosive, so there should be no open sources of fire nearby!
After removing the pump unit, when work is being done somewhere on the table, the neck opening of the gas tank must be temporarily covered with a dense layer of material: clean film or cloth. In this case, you should not close the car doors, since the interior will be ventilated through them. By the way, it is much better if the work of replacing the fuel filter is carried out outdoors.
Step-by-step instructions for replacing the fuel filter on a Toyota Corolla body 120
- The Toyota Corolla 120 fuel filter is accessed by removing the rear passenger seat on the left side of the cabin.
- Next, remove the underbody upholstery located under the seat. To do this, use a “10” key to unscrew the two fasteners (red arrows). Use a screwdriver to remove the piston (yellow arrow).
- We lift the carpet onto the seats. We secure it with the driver's and passenger's seat belts using the red protrusions. Under the mat we see a layer of foam that needs to be removed.
- Now you will see the fuel pump cover, which you can carefully pry up and remove using a knife or flat screwdriver (it sits on the black sealant).
- Before proceeding directly with the replacement, you should thoroughly vacuum the opened cavity, first under the rug, and then above the gas tank.
- Before disconnecting the pipes, we substitute a previously stored canister to drain the remaining gasoline. Next, remove the fuel hoses. The small pipe or return hose can be removed very easily; just pull the yellow bracket to the side with a thin screwdriver. Disconnecting the second hose will also not take much effort, however, if something happens, you can also help yourself with a screwdriver.
- Before directly dismantling the fuel filter, when the pipes are pulled out, you need to start the car and wait two to three minutes until it stalls. As soon as the engine turns off, you can crank the starter a few more times. This process will remove all fuel from the system and also relieve pressure.
- Next, you need to disconnect the battery terminals.
- Next, you should unscrew the eight screws with a Phillips screwdriver or an “8” key and remove the pump unit. Rags will come in handy here, as gasoline will leak out from all the cracks.
- To get to the fine filter and replace consumable components, we begin to disassemble the fuel pump.
- Remove the latch to disconnect the float.
- Next, press the plastic clips in a circle to disconnect the block body at the top.
- Apply slight force to pull the fuel pump out of the rubber seal.
- We insert the fuel pump into the new fine filter housing.
- Then you should rinse and blow out the intake mesh with compressed air and reassemble everything in the reverse order.
If you make the replacement according to all the rules and do not forget the rubber sealing rings, then the engine will start without problems and will work better than before.
Another modification of the Toyota Corolla model with a 150 body produced in 2008 has a large plastic ring with a rubber seal instead of a metal gas tank cap. To remove the block, the ring must be turned counterclockwise to loosen the seal. You can unscrew the ring lid using wooden choppers, which should be placed on the ribs of the lid and carefully hit them with a hammer.
During further disassembly, some parts may differ from the design of a Toyota Corolla with a 120 body until 2008. For example, the intake mesh and fine filter look a little different, otherwise everything is almost the same. In general, the replacement process is identical, so you can use the above instructions for a Toyota Corolla with a 120 body.
Step-by-step instructions for replacing the filter element and pump
Changing gas filters is important to maintain engine power, avoid problems when starting it, and to extend the life of pistons, piston rings, connecting rods and pins.
Replacing the gas filter in a Toyota Corolla in the 120 body is carried out independently, if the owner of the car has an understanding of working with tools of medium complexity.
Spare parts and tools
Before you change the fuel filter on your Corolla, you need to prepare. To do this, you should prepare the necessary tools and materials in advance. We will need:
- coarse gas filter;
- fine fuel filter;
- narrow slotted screwdriver for fasteners;
- Phillips head screwdriver.
- 8 wrench,
- hairdryer
Also prepare a large amount of rags and a container of water.
Execution of work
The Corolla fuel filter is located in the tank and is part of the fuel pump module, consisting of:
- fuel pump;
- primary gas filter - a component that cleans fuel from excess moisture and various impurities;
- final filter - a component that carefully filters fuel from smaller particles;
- float indicating the amount of fuel.
Before starting work, you should drain the fuel from the system so as not to flood the car interior with it later. To do this, you need to pull the fuse out of the fuse box and leave the engine idling until the fuel pump and line are empty and the engine stalls. Next, open the gas tank cap to release the pressure. It is also recommended to replace filters on the Toyota Corolla e120 with a small amount of fuel remaining in the tank.
First you need to disconnect the negative terminal of the battery. Then remove the rear seat, secured with two latches and a guide. This must be done with sudden movements. Under the seat there is a gas tank cavity cover with wires connected to it. The cover is secured with sealant and lifted using a flat-head screwdriver. This frees up the entrance to the small space above the tank where the fuel system unit is installed. To prevent dirt from getting into the tank, you need to clean with a vacuum cleaner under the place where the seat was, and then above the tank itself.
Next, unscrew the 8 bolts and remove the fuel pump. This should be done at an angle due to the float, which is attached to the wire at a sufficient distance.
Now you can assess the degree of contamination of the tank and coarse mesh. The degree of contamination of the fine gas filter cannot be seen.
The next task is to disassemble the fuel module. To do this, remove the float by bending the plastic latch. Then the mesh is removed and the fine filter, which is secured with a rubber gasket, is disconnected.
When disassembling an old gas filter, it is important not to lose the rubber bands, in case new ones were not purchased. The most difficult thing to remove is the rubber band from the top of the gas tank.
We insert the rubber bands into the new filter element, similar to the location in the old one, and complete the structure. It is problematic to replace the coarse filter and the retaining retaining ring.
Now we return all the parts to their place in the sequence in which they were removed. We tighten the nuts again and connect the tubes. But before you put the seat back in place, it’s worth checking how the system works. To do this, insert the key into the ignition and turn it to the “ON” position, but without starting the car. The operation of the fuel pump should be audible. The sound should be familiar. The metal tank cap is installed using the same sealant, after which the rear seat can be replaced.
Possible troubles and difficulties
After replacing and placing the fuel pump in the fuel tank, the car may not start the first time. The reason for this may be poor sealing of the fuel pipes, as a result of which the fuel pump does not create sufficient pressure in the line.
When disconnecting the hoses from the body, you should be careful. The system retains pressure and fuel may spray into the passenger compartment or eyes. It is worth stocking up on enough rags for cleaning.
You should also be careful about fire and sparks near the work site, because... After removing the cap, gasoline vapors from the tank quickly fill the interior.
How often should I replace it?
Replacing the Toyota Corolla fuel filter in 120 (2000-2007) and 150 (2008-2012) bodies is not provided by the manufacturer as a routine operation. Such work is performed only at the beginning of diagnostic procedures, if a drop in pressure is detected when the load on the engine increases (that is, at times when the engine’s fuel consumption is highest).
Considering that the fuel filter is built into the body of the fuel module and is not cheap even in its non-original form, few people will decide to perform such a procedure as a preventive measure, especially since it is quite labor-intensive. We also recommend performing this procedure first when purchasing a car with more than 70-80 thousand kilometers or when there are specific signs of excessive filter contamination.
Choosing a fuel filter for Toyota Corolla
To search for non-original substitutes, you need to focus on the following factory assembly numbers:
- 120 body, production from January 2002 to June 2004 – 77024-12010
- 120 body, production from June 2004 to February 2007 – 77024-02040
- 150 body – 77024-12030
The cardinal difference here is the price: original filters for a 120 body cost about 1,500 rubles, while for a 150 body the price exceeds 4 thousand. Therefore, it is not surprising that for this particular model there is a more affordable non-original in the form of JS Asakashi FS21001 and Masuma MFF-T138.
For the 120 body, non-original filters are difficult to find, but the price of the original is not so high. You will also need a filter o-ring - its number is 90301-04012.
Recommendations for choosing a filter element for a Toyota Corolla car
When choosing a new fuel filter, you should pay attention to the product part number and manufacturer's brand.
The best replacements for Toyota Corolla are the modules from the same company:
- universal version 77024-12050, which is compatible with most Corolla cars (cost - 5.5 thousand rubles);
- modification 77024-12030 for body 150 (from 4.5 thousand rubles);
- original Toyota filter 23217-0 D 090 for body 120 (from RUB 700).
When replacing, you need to focus on the compatibility of the model with the manufacturer’s recommendations for this brand.
Universal version of filter element 77024-12050.
Instructions for replacing the fuel filter
Before replacing the fuel filter, you need to drain the tank as much as possible, without, of course, bringing the level to critical - otherwise, along with the filter, you will have to change the fuel pump. If you do not empty the tank, then when removing the fuel module there is too great a risk of gasoline spilling into the cabin.
In the future, we will write about cars in the 150 body, since replacing the fuel filter with your own hands on both models is similar in principle, but here it is somewhat more complicated. Let's start by accessing the gas tank flap, which is located under the rear seat of the car.
On the 120 body the hatch is round, glued to non-drying mastic. At 150 – egg-shaped, attached in exactly the same way.
Now you need to start the engine and at the same time disconnect the connector from the fuel pump - the engine will generate almost all the pressure in the line, and when disconnecting the fuel supply pipe there will be no risk of getting a jet of fuel under pressure.
Disconnect the fuel supply pipes, fan and adsorber. Before doing this, you should wash the fuel pump cover - it is better to work with the fuel system with clean hands. The fuel pump is held in place by a shaped nut. You can unscrew it without the original puller by giving a few tangential blows to the edge - after that you can tighten it with your hands.
We remove the fuel pump, being careful not to spill fuel into the cabin. Now you need to separate the filter assembly from it - the order of operations is easy to understand by placing a new part next to it. Having removed the pump itself from the assembly, we change the sealing ring and the fuel inlet mesh on it.
We fix the new fine filter in place and connect the pressure pipe to it.
Now you can install the assembly in place, paying attention to the fact that it sits evenly before tightening the nut - otherwise the sealing ring of the cover will not fit tightly.
Procedure
The procedure should be performed in stages. First, remove the negative terminal from the battery to de-energize the fuel system. Then provide access to the part: to do this, you need to remove the bottom upholstery under the rear left seat in the cabin, this allows you to open the lid of the fuel tank cavity.
Removing the fuel pump cover
The cover must be removed. Since it is fixed to the sealant, you will need to pry it off with a screwdriver. Before you start replacing the filter, you will need to vacuum the areas under the bottom upholstery and the container itself.
After this, you need to open the connector that powers the fuel pump. In order to relieve pressure in the fuel system, you need to try to start the engine several times. If this is not done, when you try to disconnect the hoses, gasoline under pressure will spray out. Open the fuel tank. Disconnect the hoses for direct and reverse fuel supply. To pull out the return line, you will need to use a screwdriver and use it to remove the lock; It is easy to recognize, it is yellow in color. Then you need to unscrew the 8 screws using a Phillips screwdriver and pull out the pump unit.
Remove the terminal and disconnect the hoses
The float is disconnected, for which you need to move the latch, after which the upper part is detached: to do this, you need to press the clips, which are placed in a circle. The fuel pump needs to be pulled out, then inserted into the new filter housing. The mesh needs to be washed and blown with air to remove dirt, then reassemble the structure in the reverse order, not forgetting to install new seals.
Old and new filters
These instructions are suitable for replacing the filter on a Toyota Corolla in the 120 body. If we talk about the modification in the 150 body, then instead of a metal gas tank cap, you need to put a plastic ring on the neck, which is equipped with a rubber seal. To remove the block, you need to twist the ring counterclockwise, and after loosening the rubber tab, remove the pump block. To unscrew the part, you can use a hammer; they need to strike carefully through the wooden attachments. The filter for a car in the 150 body is slightly different in design: it has a different intake mesh, and the fine cleaning device comes separately.
