4 signs that your car's fuel filter is clogged and needs to be replaced
(Baonghean.vn) - The car's fuel filter is responsible for filtering out dirt in the fuel tank, ensuring a full and continuous supply of fuel when the vehicle is operating. At the same time, it ensures a long life for the engine when operating. Below are signs that the fuel filter is clogged and needs to be replaced.
- 1. The car won't start, starts unevenly, or starts but won't run.
When starting the car and it cannot start, it is very likely that the fuel filter is too dirty and gasoline cannot pass through to the combustion chamber. Specifically, when trying to increase the throttle, the car will make a reluctant popping sound of the engine due to lack of fuel. Or the car is difficult to start, takes a long time to start, the start does not sound smooth, or it starts but does not run as if the car is lacking fuel.
The reason is that the fuel filter is clogged, so the amount of fuel passing through it is small and not enough to provide the necessary level for the engine. To make the car run, press the accelerator pedal several times to increase the pump force, to provide enough fuel for the car to run. After that, you should go to the maintenance center to fix the car's condition.
2. Strange noise from the machine
If after the engine has started, a minute after the engine has warmed up, you can still hear noises coming from the engine, like a clanking or “ticking” sound, it could be a sign of a clogged filter.
The cause is due to the fuel filter being clogged or too dirty, causing insufficient fuel to enter the engine, causing the pressure in the engine head to drop, reducing combustion chamber pressure and creating a knocking sound.
When the car has this condition, it must be handled as soon as possible. The car should be checked to replace the fuel filter.
3. Phenomenon of engine starting outside or quitting

External explosion is a phenomenon where the combustion process does not take place in the cylinder but outside the engine, right in the exhaust pipe. In this case, sparks will be seen flashing out of the exhaust pipe. Or the explosion phenomenon does not continue continuously, some cylinders explode, some cylinders do not explode, called misfire.
When these situations occur, the vehicle naturally does not have enough power to maintain steady movement. It is best to bring the vehicle to the garage as soon as possible to have the filter and fuel tank filter cleaned or replaced.
- 4. Fuel-consuming car
Not only is it difficult to start, run jerkily and make unpleasant noises, a clogged fuel filter also makes the engine consume more fuel than usual.
The cause is due to clogged fuel filter, so the amount of fuel supplied to the engine is uneven. When there is not enough fuel, the engine is difficult to start and loses power, reducing capacity; when there is too much fuel, it does not burn completely and is released outside, causing waste and environmental pollution.
According to manufacturers' recommendations, fuel filters should be replaced periodically as a necessary maintenance task; fuel filters should be replaced every 2 years or every 50,000 km.
At the same time, you must check all the items, even the fuel tank, and find the cause. Thus, to keep the car running at its best, you need to pay attention to prevent disease.
