Fuel Pump Pickup Filter: Description and Operation
FUEL STRAINER
The fuel strainer is made of woven plastic. The functions of the fuel strainer are to filter the contaminants and to wick the fuel. The fuel strainer attaches
to the bottom of the fuel pump inside of the fuel sender reservoir. The fuel strainer normally requires no maintenance. Fuel stoppage at this point
indicates that the fuel tanks contain an abnormal amount of sediment. If the fuel strainer is plugged, refer to Fuel System Cleaning.
