What is a Fuel Filter?
A car’s fuel filter is located along the fuel lines, either in the engine compartment or underneath the car by the fuel tank. It is the responsibility of the fuel filter to trap large particles in the fuel in order to prevent them from getting into the engine. Because of the tremendous force behind the up-and-down motion of the engine’s pistons, which compress the air-fuel mixture so that it will burn more efficiently, any large particles in the fuel could potentially cause serious damage to the engine. Large particles in the fuel also have the ability to clog fuel injectors, depriving a cylinder of precious fuel and requiring that the injector be cleaned or replaced. Therefore, maintaining a clean fuel filter is imperative to the performance of a car’s engine. Due to the differences in fuel delivery systems, each fuel filter is different. A carbureted engine, which essentially uses the principle of vacuum to suck fuel into the engine, has a fairly low-pressure fuel system. Fuel in a c
