OTHER FILTERS AND STRAINERS

Fuel Pump/Fuel Gauge Sending Unit (typical):

A woven plastic filter is located on the lower end of the fuel pick-up pipe in the fuel tank. This filter prevents dirt from entering the fuel line and also stops water from entering the fuel system, unless the filter becomes completely submerged in water. This filter is self-cleaning and normally requires no maintenance. Fuel blockage at this point indicates that the fuel tank contains an abnormal amount of sediment or water. Therefore, the fuel tank should be removed and thoroughly cleaned and the tank filter replaced.
