Fuel system
The injection pump is bolted onto a separate bracket on the left side of the engine.The injectors (1) used
are made by Bosch. Their opening pressure is adjusted by means of washers of varying thickness inserted
above the spring.
The fuel filter (2) is attached to a filter bracket. A bleeder nipple is also placed on the bracket (3).
From the feeder pump fuel is forced through the filter and into the injection pump feed side via the fuel
shut-off valve. Return fuel from the injection pump goes via the fuel shut-off valve and overflow valve (8)
to the tank. The leak-off line from the injectors is connected to the injection pump via the suction line
connection.
