Clean fuel is important because there are small jets and passages in the openings of your fuel system, especially in carburetors and fuel injectors. The fuel filter is responsible for keeping the smaller contaminants in the system out of the engine and other fuel delivery components. To ensure this cleanliness, fuel filters are installed in the fuel line. Filters can be located at any point between the fuel tank and the engine fuel rail. The most common placement is mounted on the underside frame rail between the fuel tank and engine. Efficient Performance demands this high volume accessory.
