When to replace car fuel filter?

When the car is difficult to start even though the spark plugs have been checked and it is not a fault with this part. It is likely related to the fuel filter.

One of the common symptoms that signals the need to replace the fuel filter is that the engine cannot start because the fuel filter is too dirty and the fuel 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.

Many people do not pay attention to the fuel filter on the car, but this is a very important part. The car's fuel filter has the task of filtering out dirt in the fuel tank, ensuring a full and continuous supply of fuel when the car is operating. At the same time, it ensures a long life for the engine when operating.

In case of unexpected occurrence of the above phenomenon, the driver can use the method of pressing the accelerator pedal repeatedly to increase the pumping force, in order to provide enough fuel for the vehicle to operate. After that, the vehicle should be immediately brought to a reputable maintenance center or repair garage to check and fix this situation.

Besides the above phenomenon, there are also some other signs that the fuel filter needs to be replaced such as the car being misfiring, consuming a lot of fuel, knocking noises coming from the car engine...
