Fuel Filter: Description and Operation

A fuel filter is used in the fuel feed pipe ahead of the fuel injection system and mounted directly in front of the fuel tank. The filter housing is constructed of steel with a quick-connect fitting inlet and a threaded outlet fitting.

The threaded fitting is sealed with an O-ring, which is replaceable. The filter element is made of paper, and is designed to trap particles in the fuel that may damage the injection system. There is no service interval for fuel filter replacement. Only replace fuel filter if it is restricted.
