What Is a Fuel Filter?

A fuel filter is an integral component of a vehicle’s fuel system, protecting it from contaminants and allowing the engine to run cleanly and efficiently. The fuel filter screens dirt, sediment, contaminants, and even rust particles out of the fuel, preventing them from entering the injectors or other parts of the engine where they could cause damage. Dirt and debris can cause unnecessary wear and tear on injectors and other components.
