Fuel Filter


The inline fuel filter is located in the fuel feed pipe ahead of the fuel injection system. Quick-connect type fittings are used on both ends of the filter. The in-tank fuel filter is located on the lower end of the fuel pickup tube in the fuel tank. The filter is made of woven plastic and prevents dirt from entering the fuel line and also stops water unless the filter becomes completely submerged in water. This filter is self-cleaning and normally requires no maintenance.
