131 Model 6042 Origin 2/04
The process to vent the high pressure fuel lines (6) involves energizing the
starter motor to rotate the crankshaft which will, in turn, pump any unwanted
air from the fuel lines.
1. To vent the high pressure fuel lines (6), loosen one fitting (7) at the
injector (8).
2. Turn the ignition key to the START position and crank the engine
for a maximum of 15 seconds or until fuel, free of air, comes out of
the injector fitting (7).
3. Tighten the fitting. Torque to 22 lb-ft (30 Nm).
4. Repeat steps 1 through 3 for each fitting until the engine runs
smoothly.
5. With the engine running, visually check for leaks. Turn ignition
switch OFF.
CAUTION:
When using the starting motor to vent the fuel
system, DO NOT energize the starter solenoid or crank the
engine for more than 15 seconds at a time; wait two minutes
between engagements.
WARNING:
KEEP CLEAR of spraying fuel. Fuel can spray
when venting high pressure lines. The fuel pressure is sufficient to
penetrate the skin and cause serious bodily injury. Wear protec-
tive clothing and safety glasses.
