Fuel shut off valve
At normal operation, the solenoid in the shut off valve is activated
and fuel is fed to the injection pump.
When the starting key is turned to 0, the solenoid valve is deacti-
vated and the flow is reversed. Thereby the feeder pump drains
the fuel from the injection pump resulting in engine shut down.
The check valve prevents return fuel from flowing into the injec-
tion pump.
