Symptoms of Clogged Fuel Filter (Cause a Car Not to Start)


Essentially, fuel filters perform a crucial role since it keeps the debris out of the gasoline in a car. Because of clogged fuel filter, the flow of gasoline through the car is impeded. As a point of fact, the hesitations in the engine result from the flow of gasoline being impeded thus resulting in abnormal combustion as well as reducing the power of the engine during acceleration. Therefore, this article emphasizes on the symptoms of a clogged fuel filter.

It is essential to replace the dirty fuel filter in view of the fact that its results in the damage of the fuel pump. Replacing a fuel filter at least once a year is typically an easy task given that it will help to prevent further damages more especially to the engine. Freezing of the car can definitely occur when the flow of the fuel is restricted toward the engine. In addition, the start of the car can have a problem due to the clogged fuel filter since it is essential for the engine to have enough gas in order to start the internal combustion process.

Symptoms of a clogged fuel filter result to the fuel starvation in a car.

Symptoms of the clogged fuel filter cause stalling of the car since the car needs a constant supply of the fuel in order to maintain efficiency of the car. The flow of the fuel helps the engine to work properly given that dirty fuel affects the flow of the gas towards the engine hence the supply of power is hindered. Stalling of the car depends on the flow of fuel towards the engine since small amount will automatically reduce the functionality of the car.

Significantly, it is dangerous for the fuel filter to clog in view of the fact that there is a serious problem experienced while starting the car. Although this is the only cause of hard start of the car but it contributes greatly towards the proper functioning of the carburetor. For any car to start it requires fire from the engine, which is the result from fuel as well, the gas generated. Failure to start it implies a very definite sign of dirty fuel filter.

WOW!!! Where did you learn to write? I am an engineer and understand the workings of an IC engine but some one else less knowledgeable would find it very difficult to understand what you are trying to say. If you are going to write educational blogs go take a class or two in English Comp. at your local community college before you try to sound ‘smart’ with poor Grammer and syntax. By the way, you could have stated the issue, effects, and resolution in about 1/4 the words used.
