Typical example
Loosen the vent screw (1) on the secondary fuel filter base.
Operate the priming lever of the fuel priming pump to eliminate any air between the fuel priming pump and the fuel filters. Note: The fuel priming pump is mechanically operated by the camshaft. If the lobe of the camshaft is acting upon the arm of the fuel priming pump, the ability to hand prime the fuel system will be reduced. If the resistance on the priming lever is low, rotate the crankshaft in order to move the camshaft lobe off the fuel priming pump arm.
Operate priming lever of the fuel priming pump by hand. Check that there is correct resistance on the fuel priming pump. Operate the fuel priming pump until fuel, free of air, comes from the vent screw.
Tighten the vent screw (1) to a torque of 20 N m (15 lb ft)
Energize the stop solenoid on the fuel injection pump. Operate the priming lever of the fuel priming pump several times.
Crank the engine until the engine starts.
Do not crank the engine continuously for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking the engine again.
Start the engine and run the engine at full load for 30 seconds. Repeat the full load condition three times. This will assist in removing trapped air from the fuel injection pump.
Return the engine to no load condition. Check for leaks in the fuel system.
