Chapter 12: Fuel system

Fuel system with in-line pump has excellent operational reliability as long as the fuel is kept clean. If contaminated fuel is filled or enters the system in the incorrect manner, the risk of malfunction or wear/ damage to the injection pump increases. Contaminants include dust particles or in the form of liquid, such as water or petrol.

The fuel in the tank is drawn up by the feed pump and pushed through the fuel filter to the injection pump’s fuel chamber. The feed pump supplies a greater quantity of fuel than the injection pump requires. Consequently, there is an overflow pipe on the injection pump, which leads off surplus fuel and maintains the feed pressure in the fuel chamber. The excess is routed away via the injector’s leak oil line back to the tank.

There is a hand pump on the fuel filter, which is used to bleed the fuel system.

The injection pump pumps fuel to the injectors, which are opened by the pressure and then spray the fuel

into the prechambers, where it is ignited by theHand pump compression heat.
