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.
Replacing the TF in the 150th body
Replacing the fuel filter on a 2008 Toyota Corolla (or any other) in the 150 body has some differences from a similar procedure on the 120 body. When replacing, make sure the O-rings are in the correct position as they maintain pressure in the fuel system. Since 2010, a safety system has been used, the essence of which is that the fuel pump operates only when the crankshaft rotates. If there is no residual pressure in the system, the starter must crank the engine much longer until the pump creates pressure in the fuel line.
Preparation
Since the design of the modules is similar, there are no special requirements for tools and workplace equipment. You will need the same tools and materials as when replacing the filter on 120 body cars.
Stages of work
When replacing the filter on the 150th case, a number of points should be taken into account:
- The fuel module is attached to the tank with a plastic threaded ring with a rubber seal. The ring rotates counterclockwise. To remove the ring, you can use a wooden rod, which is attached to the edges of the ring with one end and lightly struck with a hammer at the other. The second option is to use gas wrenches that attach the ring to the ribs.
- The module has additional fuel lines for ventilation of the tank cavity. Disconnecting the hoses is similar.
- The module has two seals. Rubber O-ring 90301-08020 is located on the fuel pump where it is installed in the filter housing. The second ring 90301-04013 is smaller and fits into the check valve fitting at the bottom of the filter.
- When reinstalling, carefully install the nut spacer. Before screwing the nut back on, first install it by aligning the marks on the nut and the housing (next to the fuel line to the engine) and then tighten it.
The main points of the process are explained in photographs.

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.
Symptoms of clogging
It is quite difficult to identify obvious symptoms of a clogged filter element. This is due to the fact that the filter capacity decreases gradually. Therefore, its clogging can be judged only by indirect symptoms. The most common manifestations of the need to pay attention to the fuel filter are:
- the engine is unstable under load;
- the car's dynamics are gradually deteriorating;
- the power unit periodically stalls, especially during intense acceleration;
- the engine does not start the first time;
- The sound of the fuel pump has changed, it feels like it is running tight.
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.
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.

To replace you will need the following:
- Phillips screwdriver
- flat screwdriver;
- clean cleaning material;
- 8 mm head with crank (optional);
- vacuum cleaner.
Detailed replacement instructions:
- Removing the rear seats. We lift the seats (without touching the backs) and, using a little force, remove their supports from the grooves of the body;
- Closer to the left side of the body is the fuel tank hatch. Carefully lift it up, using a flat-head screwdriver to help in a circle if you do not remove it manually;
- Under the hatch, by pressing the lock button, remove the power chip and put it aside;
- Remove dust or vacuum the area under the lid;
- Relieve pressure from the system. To do this, with the fuel pump chip turned off, start the engine and let it run until it stalls.
- Disconnect the return pipe. To do this, pull out the yellow bracket (if you can't pull it up and out the first time, you can spread the ends with a flathead screwdriver to make it easier to remove) and with a little force, pull it up and disconnect it. Wipe up spilled gasoline with a clean cloth.
- Disconnect the supply hose. To do this, press on the mounting brackets on the sides of the end of the tube and disconnect. Clean up spilled gasoline using a cleaner. It can be much greater than in the previous case if the pressure is not relieved;
- Using a Phillips screwdriver (or an 8mm socket with a handle), remove the 8 screws that secure the fuel pump cover;
- Remove the cylinder carefully so as not to damage the fuel level sensor float;
- Disconnect the fuel level sensor terminal;
- By pressing the clamps in a circle, disconnect the top of the case;
- Disconnect the fuel level sensor. To do this, press on it until the fasteners come out of the grooves.
- Disconnect the fuel pump connector (from the pump itself, not from the upper part of the housing);
- Similarly to the upper part of the housing, disconnect the lower part where the pump is located. We will not lose the lower bushing;
- We take out the fuel pump along with the seal;
- Remove the primary fuel filter. To do this, use a screwdriver to carefully pry the fixing cap at the point of attachment to the pump, then remove the filter;
- Disconnect the outlet return fitting (at the bottom of the body) and the o-ring with the valve (at the top);
- We take a new fuel pump and install all the elements on it in reverse order.
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.
