Fuel Filter: Description and Operation

A fuel filter is used in the fuel feed pipe ahead of the fuel injection system. The fuel filter is mounted on the right side of the underbody. The fuel filter housing is constructed of steel (1) with a quick-connect fitting at the inlet of the fuel filter and a quick-connect fitting at the outlet of the fuel filter. The filter element is made of paper (2) and is designed to trap particles suspended in the fuel that may damage the injection system.

There is no service interval for in-pipe fuel filter replacement. Only replace the in-pipe fuel filter if it is restricted.
