2. (This step not required for Cummins Turbo
engines with Bosch fuel injector. Continue with
step 3.) To vent the injection pump, open the
governor vent screw and the injection pump vent
screw. Turn the ignition key to the "RUN" position
and energize the starter solenoid for 15 seconds
while operating the hand plunger on the lift pump.
Continue to pump fuel while closing first the
injection pump vent screw and then the governor
vent screw.
Warning
Fuel will spray when venting high pressure fuel
lines. Keep clear of spraying fuel. The pressure of
the fuel in the high pressure lines is sufficient to
penetrate the skin and cause serious bodily injury.
Wear protective clothing and safety glasses.
3. To vent the high pressure fuel lines, loosen one
fitting at the injectors (Figure 41). Turn the
ignition key to the "START" position and crank the
engine for a maximum of 15 seconds or until fuel,
free from air, comes from the injector fitting.
Tighten the fitting. Repeat procedure for each
fitting until engine starts and runs smoothly. With
engine running, visually check for leaks. Turn
ignition switch OFF.
