FUEL FILTERS
Two fuel filters are usually installed on Perkins Marine Engines, one in the fuel transfer pump and the other, a self
contained unit with renewable element, mounted on the engine. 4.108 engines do not have a filter in the fuel transfer
pump. A fine wire mesh filter within the fuel tank filter and a water trap between the tank and transfer pump are highly
recommended to pre-filter the fuel.
