FUEL SYSTEM 20D
To eliminate air from the fuel system
Lucas DP200 pump20D-08
Air will usually be removed from the fuel pump
automatically. If the fuel system is empty or if the
canister of the fuel filter has been renewed, it will
be necessary to eliminate air from the fuel system.
1 Release the vent plug on the fuel filter head (A).
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.
3 Loosen the union nut (C1) at the fuelled starting
aid, if one if fitted, 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 high-pressure connections at two of
the atomisers (D1).
5 Ensure that the manual stop control, if one is
fitted, is in the "run" position. Operate the starter
motor until fuel, free of air, comes from the pipe
connections. Tighten the connections to 22 Nm
(16 lbf ft) 2,3 kgf m.
6 The engine is now ready to start.
