The fuel filter/water separator is located directly above the starter motor on the left hand side of the engine. The fuel filter element is removed from the housing after all water (if present) has been drained from the assembly" Diesel engines
Drain all the water and diesel fuel from the housing assembly as follows:
Place a drain pan under the drain hose.
With the engine OFF, either rotate the valve to "DRAIN" or lift the valve upward (depending on model) until all water and contaminants have been removed and the fluid stream is clear fuel.
If the filter is being replaced, drain the housing completely until all water and fuel is removed.
After the filter/separator is empty, close the valve handle.
Remove the fuel filter cap by removing the nut on top of the canister. On late models the "nut" is part of the cap.
The fuel filter will be removed with the cap.
Inspect the o-rings for cracks, distortion, or any other signs of deterioration. Replace as needed.
Clean and inspect the inside of the canister.
Install new o-ring(s) as needed.
Install the proper filter element in the canister.
Fill the canister with clean diesel fuel.
If the canister is not filled with clean diesel fuel prior to installation, manual air bleeding of the system will be necessary, follow the procedure outlined in "DRIVEABILITY AND EMISSION CONTROLS."
Apply a coating of diesel fuel to all seals.
Position the cap to the canister. On 1997-99 models, be sure the locating tabs are properly lined up to avoid breaking the canister or having the drain valve handle contact the throttle linkage.
Install the canister cap. On 1997-99 models, install and tighten nut to 10 ft. Lbs. (14 Nm). On later models, tighten cap to 25 ft. Lbs. (34 Nm).
Start engine and check for leaks by holding a piece of cardboard around seal area. Check cardboard for signs of diesel fuel.
