2.2.8. Fuel system

The fuel is delivered by the fuel lift pump via the fuel filter to the injection pump and from there to the

injectors.

The fuel is sprayed into the cylinder through nozzles fitted in screw-fit injections in the cylinder heads.

Excessive fuel delivered and leak fuel from the injectors flow through the return pipe back to the tank.
