Circuit/System Description

Fuel is drawn by the fuel injection pump through a pre-filter screen in the tank. Fuel flows to the diesel fuel conditioning module (DFCM), which combines a water separator, an electric fuel prime pump, fuel heater element, and a filter element. The fuel is then delivered to a second screw on fuel filter and the high-pressure pump. An integrated electric fuel prime pump is used to prime the fuel system after changing the fuel filter or servicing the fuel system. The mechanical fuel injection pump at the front of the engine valley includes the fuel supply pump and the high-pressure pump.
