Fuel Filter: Description and Operation

A stainless steel in-line fuel filter is used in the fuel feed line ahead of the fuel injection system. The steel filter housing (1) is constructed to withstand maximum fuel system pressure, exposure to fuel additives, and changes in temperature. The filter element (2) is made of paper, and is designed to trap particles in the fuel that may damage the injection system. A quick-connect type fitting is used at one end and an "0" ring where the fuel pipe screws into the fuel filter body on the other end. There is no service interval for fuel filter replacement. Replacement is required only if the fuel filter becomes restricted.
