Fuel Filter: Description and Operation

In-Line Fuel Filter (Typical):

A steel in-line fuel filter is used in the fuel feed pipe ahead of the fuel injection system. The filter housing is constructed to withstand maximum fuel system pressure, exposure to fuel additives, and changes in temperature. The filter element is made of paper, and is designed to trap particles in the fuel that may damage the injection system. Quick-connect type fittings are used at both ends of the filter. There is no service interval for fuel filter replacement. Only replace fuel filter if it is restricted
