2.6. Fuel System
The fuel is delivered by the fuel feed pump via the fuel filter to the injection pump and from there
to the injection nozzles.
The fuel is sprayed into the cylinders through nozzles fitted in screw-fit injection nozzle holders
in the cylinder heads.
Excessively delivered fuel and leak fuel from the nozzle flow through the return pipe back to the
tank.
A strainer is arranged ahead of the fuel feed pump.
