1. Loosen the vent screw located on the fuel fitting outlet of the fuel filter.
2. Operate the priming pump until a steady flow of fuel comes out of the vent screw. Tighten the vent screw.
3. Loosen the injection fuel line fittings at at least two of the injectors.
4. Disconnect the control wire to the glow plug relay and then crank the engine until fuel comes out of the loosened fuel lines.
5. Tighten the fuel line nuts to a torque of 18 ft. lbs. (25 Nm).
6. Reconnect the glow plug connector and start the car. Check carefully for fuel leaks around the vent screw and the injector nuts.
