1. FUEL SYSTEM DESCRIPTION
Figure 1 shows a schematic of the fuel system. Fuel is drawn from the fuel tank through a manual shut-off
valve, a primary fuel filter or a fuel filter/water separator (optional) before it enters the fuel pump. If the
vehicle is equipped with the optional “Davco Fuel Pro 382”, it is designed to be the only fuel filter in the
system, no secondary fuel filter is necessary. Leaving the pump under pressure, the fuel flows through a
secondary fuel filter and a shut-off valve, then to the cylinder head. The fuel reaches the injectors in the
cylinder head through passages within the head. Excess fuel exits at the rear of the head just above the
inlet, through a restrictive return fitting which maintains fuel pressure in the system. Finally, the fuel flows
through the check valve and the fuel cooler before it returns to the fuel tank.
