Schematic overview of fuel. syst.
Caution! To avoid running the high pressure pump dry (very tight tolerances) and in order to quickly start the engine after replacing parts, the following points must be observed. When removing or replacing fuel parts/components. the first fuel filling must be carried out between the fuel tank and the high-pressure fuel pump. after removing or replacing the fuel injection pump, it is necessary to bleed the fuel before starting the engine for the first time. syst.
