High-Pressure Fuel Pump
The high-pressure fuel pump is located under the intake manifold, behind the coolant and vacuum pump assembly. The
fuel pump is driven by the timing chain at the front of the engine and includes a transfer pump and a high pressure
pump which are serviced as one unit.
The pump provides the interface between the low and high-pressure systems. Its function is to always provide sufficient
compressed fuel under all operating conditions and for the entire service life of the vehicle.
The transfer pump draws the fuel from the fuel tank, through the fuel filter, and then pumps the fuel to the high-
pressure pump. The transfer pump maintains a constant fuel pressure through a regulating valve within the fuel pump;
this is known as transfer pressure.
The high-pressure pump receives fuel at transfer pressure from the transfer pump and increases the fuel pressure. The
high pressure fuel is then transferred from the high-pressure pump to the common rail.
