20A FUEL SYSTEM
Fuel lift pump
To remove and to fit20A-03
1 If a heat shield is fitted, remove it. Disconnect
the fuel pipes from the fuel lift pump.
2 Release the setscrews, remove the lock plates
and remove the fuel lift pump (A). The lift pump
may be difficult to remove from the engine. If this
occurs the crankshaft must be rotated until the
camshaft eccentric, that operates the lift pump, is in
a position which will free the rocker lever of the lift
pump.
3 Ensure that the camshaft eccentric is in the
minimum lift position before the lift pump is fitted.
Clean the joint face of the lift pump and the cylinder
block and fit the lift pump together with a new joint.
Fit the lock plates and the setscrews and tighten
them gradually and evenly to 22 Nm (16 lbf ft) 2,2
kgf m.
4 Connect the fuel pipes and, if necessary, fit the
heat shield.
5 Release the vent screw on the fuel filter head
and operate the priming lever of the fuel lift pump to
eliminate any air between the lift pump and the fuel
filter. Operate the lift pump until fuel, free of air,
comes from the vent screw. Tighten the vent
screw.
6 Operate the engine and check for any fuel or air
leakage.
To dismantle and to assemble20A-04
To dismantle
