Contaminants such as dirt, rust or even poor quality fuel can be potentially harmful to an engine by causing inefficient combustion, blocked or worn injectors, and even damage to the engine itself. The purpose of a fuel filter is to ensure that only the cleanest possible fuel is fed to your engine in order to keep it healthy and fuel efficient. For the most effective filtration, not only must a superior quality fuel filter be used, but it must also be replaced on a regular basis to ensure consistent performance.
