Fuel System Service

Priming Fuel System
1. Stop the engine. Unlatch and raise the hood
2. Fill the fuel tank.
3. Install a 3/16" hose over bleed screw. Put other end
of hose into a container to catch fuel (Fig. 38).
4. Pump priming plunger until resistance is felt. Try to
start engine. If engine does not start, go to step 5.
5.Loosen bleed screw a few turns. Pump priming
plunger until a steady stream of fuel comes out of hole
in bleed screw. When fuel stops foaming, tighten bleed
screw during down stroke of priming plunger. Wipe up
any spilled fuel.
NOTE: It may be necessary to bleed air out of the fuel
line, between the fuel filter/water separator and the
injection pump. To do this, loosen the fitting on the
injection pump (Fig. 39) and pump priming plunger until
a steady stream of fuel comes out of fitting. When fuel
stops foaming, tighten the fitting during the down stroke
of the priming plunger. Wipe up any spilled fuel.
NOTE: The high pressure fuel system is self-bleeding.
It is not necessary to open the high pressure lines.
