The fuel filter in your vehicle strains and cleans the fuel so it can be burned in the engine. Some fuel filters will also separate water from the fuel to prevent it from reaching the engine. Fuel filters come in many styles, and the fuel filter used in your vehicle depends on its make and model.

Dirt and debris can enter your vehicles fuel tank when refueling or using lower-quality fuel. These particulates can clog fuel jets and fuel injectors and cause the fuel to burn dirtier, producing excess carbon build-up in your engine. The fuel filter removes these particulates before entering the engine, keeping fuel injectors and jets clear and free-flowing and reducing carbon deposits in your engine to sustain performance.
