Standard method to eliminate air from the fuel system
1 Loosen the banjo connection bolt which is fitted on the top of the filter (A1).
2 Operate the priming lever on the fuel lift pump (B) until fuel, free from air, comes from the filter vent point.
Tighten the banjo connection bolt. If the drive cam of the fuel lift pump is at the point of maximum cam lift, it
will not be possible to operate the priming lever. In this situation, the crankshaft must be turned one revolution.
3 Where the fuel filter is fitted lower than the fuel injection pump, loosen the inlet connection at the fuel injection
pump (C3) and operate the lift pump to remove any air. Tighten the inlet connection.
4 Ensure that the manual stop control is in the “run” position. If an electrical stop control is used, turn the start
key to the “R” position.
5 Loosen the vent screw in the lock screw of the hydraulic head (C1) and the vent screw on the governor cover
of the fuel injection pump (C2).
6 Operate the priming lever of the fuel Iift pump until fuel, free from air, comes from the vent screw(s). Tighten
the vent screw(s).
