How to eliminate air from the fuel system
If air enters the fuel system, it must be eliminated before the engine can be started.
Air can enter the system if:
z
The fuel tank is drained during normal operation.
z
The low-pressure fuel pipes are disconnected.
z
A part of the low-pressure fuel system leaks during engine operation.
In order to eliminate air from the fuel system, proceed as follows:
1 Loosen the vent plug (A1) on the top of the fuel filter head.
2 Operate the plunger of the fuel priming pump (A2) until fuel, free from air, comes from the filter vent point.
Tighten the vent plug.
3 Turn the start key to the "ON" position.
4 Operate the starter motor for intervals of 15 seconds until the engine starts. If the engine runs correctly for
a short time and then stops or runs roughly, check for air in the fuel system. If there is air in the fuel system,
there is probably a leakage in the low pressure system. Turn the start key to the "OFF" position to stop the
engine. Rectify the leakage and repeat the procedure.
