To eliminate air from the fuel system
Lucas DP200 pump
20-12
Air will usually be removed from the fuel pump
automatically when the engine is in operation. If the
fuel pipes are disconnected or if the canister of the
fuel filter has been renewed, or the engine runs out of
fuel, it will be necessary to eliminate air from the fuel
system.
Caution: If the fuel system is empty or if the
canister(s) of the fuel filter have been renewed, it will
be necessary to eliminate air from the fuel system,
especially the fuel injection pump.
1 Release the vent plug on the fuel filter head (A1).
2 Operate the priming lever of the fuel lift pump (B)
until fuel, free of air, comes from the vent plug.
Tighten the vent plug. If the drive cam of the fuel lift
pump is at the point of maximum lift, it will not be
possible to operate the priming lever. In this situation,
the crankshaft must be rotated one revolution.
Caution: Use a spanner to prevent movement of the
fuelled starting aid (C1) when the union nut (C2) is
loosened or tightened.
3 Loosen the union nut (C2) at the fuelled starting aid
and operate the priming lever of the fuel lift pump until
fuel, free of air, comes from the connection. Tighten
the union nut at the starting aid.
4 Loosen the union nut at the outlet connection of the
low pressure fuel leak off pipe which is on top of the
governor housing of the fuel injection pump. Operate
the priming lever of the fuel lift pump until fuel, free of
air, comes from the connection. Tighten the union nut.
Caution: Do not tighten the union nuts of the high-
pressure pipes more than the recommended torque
tension. If there is a leakage from the union nut,
ensure that the pipe is correctly aligned with the
atomiser inlet. Do not tighten the atomiser union nut
more, as this can cause a restriction at the end of the
pipe. This can affect the fuel delivery.
5 Loosen the high-pressure connections at two of the
atomisers (D1).
