FUEL LIFT PUMP REPLACEMENT - CONTINUED
Cleaning compound, solvent MIL-PRF-680 Type III is an environmentally compliant and low toxic mate-
rial. However, it may be irritating to the eyes and skin. The use of protective gloves and goggles is sug-
gested. Use in well-ventilated areas. Keep away from open flames and other sources of ignition.
Clean fuel tube (14) with cleaning compound, solvent.
The fuel injection pump needs fuel for lubrication. The precision parts of the fuel injection pump are
easily damaged. For this reason, the engine must NOT be started until the fuel injection pump is full of
fuel that is free of air.
The system must be primed any time any part of the system is drained of fuel. For example, when the
fuel system is changed or a fuel line is removed or when the inspection cover on the fuel injection pump
is removed for service or repair, the fuel system must be primed (air removed).
Ensure camshaft lobe is turned away from lever before installing fuel lift pump.
Ensure mating surfaces of engine block and fuel lift pump are clean and free of old gasket and oil mate-
rial prior to installation.
