How fuel filter work
From time to time, cars need to be refueled in order to move on the roads, as fuel is a very important element for engines, and for the gas that is supplied to cars, it is located in large tanks under gas stations, it is pulled from the hose to the car's tank with the push of a button.
When you refill your car's tank with gas, it must be mixed with some of the dirt and impurities that are in it either during the refining process or during its transportation from large stations to gas stations via trucks, or through dirt that may be present in the station's tanks.
In order to prevent this dirt from entering the engine and damaging its sensitive internal parts, cars are equipped with a special fuel filter that purifies gas from impurities and dirt before it enters the engine, and the filter is usually close to the engine, especially in older cars, or it is inside the fuel pump in modern cars.
If you want to know the location of the fuel filter in your car, you can refer to the owner's manual and know the rest of the details of the fuel system, if the filter is external, it is replaced, but if it is inside the fuel pump, it is not replaced and may not need to be cleaned at all.

What are the symptoms of a clogged fuel filter
As for the symptoms of a clogged or damaged fuel filter in your car, they are as follows:
Poor engine performance
One of the most important symptoms of a clogged or damaged fuel filter is to notice the poor performance of the engine, and you will notice that it struggles to accelerate or you may lose the ability to accelerate due to the slow process of transferring fuel from the tank to the engine due to the dirt that is in it, so you will feel the weakness of the engine at high speeds.
Fluctuating engine operation
A clogged fuel filter can disrupt the flow of fuel to the engine, leading to interruptions in the delivery of fuel to the engine and causing the engine to oscillate, so you will notice the engine shaking, intermittent work, or maybe it stops working altogether.
Increased fuel consumption
A clogged fuel filter can lead to increased fuel consumption, as the engine control device reads the incorrect air-fuel mixture information due to the clog, and gives a command to pump more fuel to the engine to get the correct amount that ensures the engine's work, and additional fuel with a clogged filter means increased fuel consumption without a doubt.
Difficulty starting the engine
If you notice that starting the engine is delayed and takes longer than usual, perhaps the fuel filter is clogged and cannot pass the required amount of fuel to the engine to start it, and if the fuel filter is damaged or severely clogged, you will not be able to start the engine at all.
Weak torque with excessive weight
When the car is parked, you may not feel the engine weakening if the air filter is clogged, but if you are putting a large load in your car or towing a trailer behind you, the engine's performance will weaken, and you will feel the loss of torque especially if you encounter a strong hill in front of you.
Check engine light appears
The yellow check engine light appears in many issues, one of these issues is fuel injectors, if the injectors are not receiving enough fuel, the check engine light will appear as a result of a clogged or damaged fuel filter, or even damage to some parts of the fuel system.
Fuel pump failure
Too much pressure on the fuel pump when it is trying to push the right amount of fuel into the engine but there is an obstruction caused by a clogged or damaged fuel filter, this will cause it to strain to the point where it may stop working, and when it stops working, the engine will stop working.
