Fuel Pump Pickup Filter: Description and Operation
A woven plastic fuel pump strainer is attached to the lower end of the fuel pump in the fuel tank. The functions of the fuel pump strainer are to filter
contaminants and to wick fuel.
The life of the fuel pump strainer is generally considered to be that of the fuel pump. The fuel pump strainer is self-cleaning and normally requires no
maintenance. Fuel stoppage at this point indicates that the fuel tank contains an abnormal amount of sediment or water, in which case the tank should be
thoroughly cleaned. Refer to Fuel System Cleaning.
A fuel filter is used in the fuel feed pipe ahead of the fuel injection system. The fuel filter is mounted directly in front of the fuel tank. The fuel filter
housing (1) is constructed of steel with a quick-connect fitting at the inlet of the fuel filter and a threaded fitting at the outlet of the fuel filter. The
threaded fitting is sealed with an 0-ring, which is replaceable. The filter element (2) is made of paper 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.
