Thanks to its versatility and well-thought-out technical characteristics, the stylish “Japanese” has gained unprecedented popularity. The dream of every owner is to drive without problems and have rare meetings with service centers. Much depends on the owner of the vehicle and the conditions he has to face.
The cleanliness of the filter element dictates the correct operation of the engine and preserves the beneficial properties invested in it by the developers longer. Let's look at how the Toyota Corolla fuel filter works. How to replace it? What will it take?
More about filters
A certain type of filter unit is installed on a car depending on the type of body and the year of its production. Before replacing, you need to select it correctly. Experts identify several species suitable for the “Japanese”.
- For Corolla-180 models, it is better to choose a product with article number 23300-28040.
- On the body of a Toyota Corolla 150, a fuel filter is installed with article number 77024-12030.
- For a 120 body, a model with a coarse cleaning system is suitable.
Do not be afraid to purchase Chinese or Korean products. If you purchase from a reliable seller, incidents with auto parts will not happen. You must consider the VIN number when choosing. Then the probability of making a mistake will be zero.
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.
About the feasibility of installing the device
For any vehicle, fuel purification plays an important role. This ensures reliability and safety of transport. In this regard, the question is where to install the Toyota Corolla fuel filter, and how it is recommended to install it.
You can install two filters in your car: one at the inlet of the fuel supply pump, the other in the area between the pump unit and the fuel rail. Why was it invented?
The task that the Toyota Corolla fuel filter is designed to cope with is to clean the fuel from impurities, dirt, and grains of sand that penetrate the engine. Changing the filter mechanism at the wrong time leads to disruption of the motor functions. It is installed on all cars and works with any type of petroleum product.
Safety regulations
When working to replace the filter under the underbody from the passenger compartment, it is very important to follow fire safety rules. Within a few seconds after removing the gas tank cap, gasoline vapors penetrate into the cabin. Their explosiveness when mixed with air is mentioned everywhere. Therefore, in no case should there be sources of sparking and, especially, open fire!
When the pump unit is removed and work is being done somewhere on the table, the neck of the gas tank should be temporarily covered with a clean film or thick rag. At the same time, you should not close the car doors - the interior will be ventilated through them. It is also preferable to keep the vehicle outdoors while working.
To install a new filter on a Toyota Corolla, you don’t have to contact a service center; you can do the work yourself. To do this, you will need a canister or other container to drain gasoline and rags. You also need a pair of sealing elements (their average cost is 200-250 rubles), two screwdrivers - with a flat head and a Phillips head.

Gasoline vapors are a strong poison for the human body. Chemical poisoning may cause headache, weakness, nausea, and dizziness. In the long term, with constant contact with gasoline, it can act as a carcinogen. Gasoline is also explosive and flammable.
Therefore, the following safety rules must be observed when replacing the fuel pump:
- Do not work in a closed or poorly ventilated area;
- Eliminate any possibility of contact with open flames (do not smoke, do not illuminate the work area with fire);
- To minimize gasoline leaks, before disassembling the flask, drain all the gasoline that is possible into an airtight container;
- If a leak occurs, use cleaning material immediately. After use, to avoid the spread of toxic fumes, place in a sealable container;
- If signs of poisoning occur, immediately leave the work area and go into the open air. If the condition worsens, seek medical help.
How it works
The peculiarity of the action is as follows: the Toyota Corolla fuel filter passes fuel through itself before it enters the combustion chamber. Cleaning is carried out in stages, thanks to which the motor is protected. How does this happen in a car that runs on gasoline?
At a gas station, fuel is poured into the gas tank. It is possible that dirt may get into the tank from the fuel supply devices. It also accumulates on the walls of the container. The submersible pump absorbs dirty fuel. Despite the presence of a nylon mesh in it, it is impossible to cope with all unnecessary particles. Such a device only helps to get rid of coarse debris, so the Toyota Corolla fuel filter is an urgent need, not a luxury. First, fine cleaning occurs, preventing small particles with dimensions less than 10 microns from entering the power unit. The owner will be required to carefully monitor its condition and change it in a timely manner.
About changing the filter element on the 120th Toyota Corolla body
I would like to immediately warn you about the strictest compliance with fire safety rules when performing this operation. Before starting work you need to prepare:
- Empty container for remaining fuel.
- Rags or rags.
- New filter element.
- Sealing gaskets.
- Flathead and Phillips screwdrivers, as well as a vacuum cleaner.
To begin removal, you need to lift the rear passenger seat of the car, and then remove the underbody upholstery. It is secured with two screws and a piston. To release them, you will need a “10” key and a screwdriver.

The mat is lifted onto the seats and secured with seat belts so that it does not interfere with further operations. It is necessary to remove the foam layer under the mat. After this, the fuel pump cover will become visible, which can be easily removed if you pry it off with something sharp. Do not begin replacement until all debris accumulated there has been removed with a vacuum cleaner.
The pipes are removed from the fuel pump and the remaining gasoline is drained into an empty canister. After this, you should start the Toyota Corolla engine to completely exhaust the available fuel in the power system. After stopping the engine, turn it over with the starter several more times and remove the terminals from the battery.
After this, you can begin to remove the block with the pump. You will need the help of a Phillips screwdriver and an “8” wrench, as well as a rag or rag for spilling gasoline. When the block with the pump is removed, you can begin to dismantle the filter element.
It is necessary to release two latches on the body and several clips. Then you can easily remove it from the case with little effort. Having taken out the old one, insert a new fine cleaning element into the fuel pump housing. At the final stage, the fuel intake mesh is washed and purged, and assembly is performed in the reverse order.
It's a question of time
Every motorist wants to know exactly when it is necessary to change the fuel filter on a Toyota Corolla 150 or on another body type. Many people are concerned about whether they can do it themselves. The designers conceived the operating scheme of the car in such a way that the filter, according to the regulations, needs to be changed after 80 thousand km. Some “dared souls” dare to ignore this rule, doubling this parameter.
Much depends on the quality of gasoline. Using domestic brands, you cannot cover a large number of kilometers without changing the filter. Rather, this can be done when using original fuel. At the service station, employees recommend stopping by for a replacement every 50,000 km. Not all beginners are familiar with the signs of a clogged filter.
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 automotive 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.
Installation process
Changing the fuel filter of a Toyota Corolla 120 body is not difficult if you have some knowledge. For a car enthusiast who is starting to master the road, it is better to consult with specialists for the first time. The service life is designed for 50 thousand km. However, this figure is calculated on a Japanese road surface with high-quality coating. The work includes several stages:
- The rear seats need to be removed.
- You will have to pry off the plastic cover with a screwdriver, moving it to the side.
- If necessary, the sealant is removed from the surface of the gas tank.
- Empty containers are prepared in advance. The hoses are carefully disconnected. This may cause some of the gasoline to spill out, so an empty container will come in handy.
- The fuel filter cover will need to be vacuumed.
- The eight bolts securing the TF cover should be unscrewed.
- Before dismantling the TF, the motor starts. Now the car enthusiast should wait until it stalls. Then the procedure is repeated.
- The disassembly of the fuel pump begins, followed by the dismantling of the float. After this, the coarse filter apparatus is dismantled.
When carrying out this simple manipulation, it is important to ensure the integrity of the rubber gaskets. When worn, they should be replaced. The old mesh and float are installed on the new filter.
When to change filters - expert recommendations
The fuel filter in a car is used to clean fuel from the tank, which may contain various debris that got in during refueling, as well as solid particles and impurities in the poor-quality fuel mixture. The operation of your engine, as well as its spark plugs, depends on the timely replacement of this part. Therefore, you should not save on purchasing high-quality spare parts - the cost of engine repairs will be much higher.
If the main filter in a Toyota Corolla is mounted together with the fuel pump in the gas tank, then the additional filter is located under the hood of the car. The device is designed to completely filter various impurities that come along with gasoline through the fuel pipes. The Toyota Corolla car manufacturer recommends replacing the filter once every 70–100 thousand km.
As practice shows, given the low quality of our fuel, it is better to do this once every 50 thousand km. Fuel filter contamination occurs gradually, and changes in the car’s performance will not be very noticeable at first.
However, when the fuel filter ceases to perform its functions, this will certainly begin to affect the performance of the car. It may not pull well, does not start the first time, and accelerates poorly. This significantly increases fuel consumption. If the filter is not replaced on time, the fuel pump may fail. This happens because the fuel pump constantly pumps the required amount of fuel for the car to operate, and a clogged filter will prevent it from doing so.
Professional recommendations for replacing the fuel filter on a Toyota Corolla 150
Experts advise adhering to the following algorithm:
- The seats in the rear seats can be raised and removed.
- A special hatch is hidden under the casing. You can get to it by removing the upholstery.
- A flathead screwdriver will help remove the cover; You can warm up the lid a little if it is difficult to remove. This is possible using a hair dryer.
- There is a lot of accumulated dust under the cover; it can be removed using a simple vacuum cleaner.
- The pressure in the system must be reduced. To do this, the pump terminal is removed and the motor is set in motion.
- If the motor stops working, dismantling operations continue.
- The supply and return pipes are disconnected by pressing on the fixing brackets.
- The lid fasteners (there are 8 of them) are unscrewed. The filter is removed, preventing gasoline from entering the body. Assembly is carried out in reverse order.
The fuel system operates normally, subject to the rules of vehicle operation and the selection of high-quality fuel. It is useful to learn about the requirements for auto parts.
Features of selection and replacement
In the auto parts market, the owner of a Corolla of both 2008 and later versions can be offered a choice of at least three types of filters - Chinese and Korean analogue parts and originals. Original products, as a rule, cost an order of magnitude more, but are high quality and reliable. How much a Toyota owner is willing to pay for a new filter element depends on his budget.
After 2008, Toyota Corolla began to be equipped with fuel filters, which, if clogged, can be changed independently of the gasoline pump, without having to replace the entire module responsible for supplying fuel to the gas tank.
You should always approach the selection process very carefully, and you must purchase exactly the fuel filter for Toyota Corolla that is suitable for the specific year of manufacture of the car and body type.
Replacement in cars produced in 2007–2008 with a 120 body
The average period for which the element will efficiently filter fuel on Corolla E120 cars is 50 thousand km. But you need to take into account that this parameter is designed for Japanese roads, the quality of which is much higher than domestic ones. Therefore, if you use a car in our country, you should change the filter every time after a mileage of 25–30 thousand km.
To make the replacement procedure quick and trouble-free, you should prepare the following set of tools and other necessary items:
- a new fuel filter, which will be installed to replace the old one (preferably original, although sometimes you come across Chinese consumables that work well);
- new O-rings (2 pieces);
- Phillips and flat head screwdrivers;
- rags;
- dishes for draining excess fuel.
First you need to remove the rear seats and remove their inner upholstery. Below it is the fuel pump cover.
Using a flat screwdriver, carefully, being careful not to damage anything, you need to remove the fuel pump cover.
Next, disconnect the hose and unscrew the 8 bolts using a Phillips screwdriver.
After all this has been done, you should start the car a couple of times and let it stall so that all the gasoline that may be in the system leaves it. Then you need to remove the battery terminals. Then the pump itself is taken out and inspected, the condition of the mesh for rough cleaning is assessed.
It is necessary to dismantle the float and remove the coarse fine cleaning elements, which we replace with new ones.
After installing the new elements, reassemble in the reverse order and install the gasoline pump in its place.
Replacement in a car with a 150 body
To replace the fuel filter on a Toyota Corolla 150, you need the same set of tools, as well as a new filter and o-rings. In this modification, the fuel pump cover is made of plastic and equipped with a rubber seal. To remove the fuel pump, you need to turn the ring counterclockwise to loosen the seal. The further replacement process coincides with the actions for the 120 body.
What happens if you ignore problems
Turning a blind eye to a stalled engine during a trip is bringing yourself and other road users closer to trouble. A worn and clogged filter leads to incorrect functioning of the machine's motor. Condensation accumulates on its components, stimulating the formation of rust.
Resins greatly reduce the operating efficiency of a vehicle. Gradually, all elements of the complex will fail, bringing the owner to serious financial costs. Problematic situations can be avoided if you change the cleaning device in time, that is, the fuel filter designed to clean the engine compartment.
The machine itself signals the appearance of defects, the main thing is to be able to listen to it and not brush aside the problem that has arisen. After all, sooner or later it will have to be resolved. If you don’t have time to bother with replacing the filter yourself, you need to contact a service center. Specialists will quickly cope with this work.
