Figure 6. Fuel Prefilter
NOTICE:
Correct torque on the high pressure lines is critical. Incorrect torques could result in leaks or lack of
power due to restricted fuel flow.
7.
To bleed the fuel system, make sure that all high-pressure lines have been tightened to 25 N·m (18 lb·ft) and all banjo
bolts to 40 N·m (30 lb·ft).
8.
If equipped with a hand pump on the fuel/water separator, work the hand pump 50 times.
9.
Crank the engine for 30 seconds at a time, but no longer. Before cranking the engine again, wait at least two minutes.
The engine should start within four 30-second attempts.
14.6 Main Fuel Filter Element Changing
Change the main fuel filter element as follows:
1.
Open the vehicle fuel tank filler cap to release pressure in the fuel system. Replace and tighten the cap.
2.
Clean the outside of the fuel filter housing. See figure below.
3.
Using a 36-mm socket wrench insert, unscrew the cap on the fuel filter and remove it, along with the filter element.
Pull both the cap and the filter element a short distance out of the filter housing. See figure below. Allow the fuel to
drain off the filter into the housing.
4.
Remove the cap with the filter element. To release the filter element, twist the lower edge of the filter element to one
side.
NOTICE:
To prevent damage to the filter housing, do not allow dirt to get into the filter housing. Do not empty the
dirt collector into the filter case.
5.
Pull the dirt collector out of the filter housing using the tabs on either side.
