Engine fuel filter
The fuel filter is a dual function fuel filter water separator with a cartridge-type filter suited for diesel engines
equipped with high pressure injection systems. An optional water-in-fuel sensor is available and can be
ordered separately.
Fuel rail high-pressure pump
The fuel rail pressure pump is a mechanical high pressure pump. Fuel is pumped to to the fuel rail at a specific
pressure. Fuel pressure is regulated by the fuel pressure regulator, which is controlled by the Engine Control
Unit (ECU) and returned through the return fuel line.
Fuel rail assembly
The fuel rail assembly attaches to the cylinder head. The fuel rail distributes pressurized fuel to the fuel
injectors through the fuel lines.
Fuel tank
The minimum fuel tank volume must be 100 liters to prevent heating of the fuel.
Fuel rail sensor
The fuel rail pressure sensor gives the ECU an indication of fuel pressure. The ECU uses this information to
regulate fuel pressure, by commanding the fuel pressure regulator open or closed on the inlet of the fuel
injection pump.
Fuel injectors
A fuel injector is a solenoid device, controlled by the ECU, that injects pressurized fuel to each engine cylinder.
Fuel from the injector tip is sprayed directly into the combustion chamber on the compression stroke of the
engine.
The control functions for the fuel injection system are integrated in the ECU.
Quick-connect fitting
Quick-connect fittings provide a simplified means of installing and connecting fuel system components.
The fittings consist of a unique female connector and a compatible male pipe end. O-rings, located inside the
female connector, provide the seal. Integral locking tabs inside the female connector hold the fittings together.
Fuel pipe O-rings
O-rings seal the connections in the fuel system. Fuel system O-ring seals are made of a special material.
Service the O-rings seals with the correct service parts.
