CHECKS AND SERVICE
Venting the fuel system
In order for the engine to be able to start, the fuel system must be vented on the following
occasions:
When changing the fine filter.
With leakage and work on the fuel lines.
When the engine has not been used for a
long time.
When draining through the drain hole.
When cleaning the fuel pump strainer.
After running the fuel tank empty.
When installing the fuel injection pump.
Venting is as follows:
1.
2.
Open the vent screw on the fuel filter.
Pump forward the fuel with the help of the hand primer until fuel free from air bubbles
flows out. Close the vent screw. If the pumping effect is poor, turn over the engine a
bit so that the pump drive cam alters its position.
3.
If the fuel injection pump has been removed, or when starting an entirely new engine
for the first time, the fuel injection pump must be vent. To do this open the vent
screw on the pump. Pump with the hand primer until fuel free from air comes out.
Slacken the injector delivery pipe nut and turn over the engine by means of the
starter motor until fuel comes from the delivery pipe. Tighten up the delivery pipe nut
and start the engine.
