How to eliminate air from the fuel system
There are two methods to eliminate air from the fuel system according to the type of pump fitted:
Standard method: This method is used on the Lucas DPA fuel injection pump. Vent screws (A1 and A2) are
fitted to this pump. Refer to "Standard method to eliminate air from the fuel system" on page 28.
Self-vent method: This method is used on the Lucas DP200 Series and the Stanadyne DB2 fuel injection
pumps. Vent screws are not fitted to these pumps. Refer to "Self-vent method to eliminate air from the fuel
system" on page 30.
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.
