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 "How to eliminate air from the fuel system (standard method)" on page 30.
Self-vent method: This method is used on the Stanadyne DB2 fuel injection pump. Vent screws are not fitted
to this pump. Refer to "How to eliminate air from the fuel system (self-vent method)" on page 32.
If air enters the fuel system, it must be eliminated before the engine can be started.
Air can enter the system if:
The fuel tank is drained during normal operation.
The low-pressure fuel pipes are disconnected
A part of the low-pressure fuel system leaks during engine operation.
