REMOVAL

Refer to maintenance schedules, or the Owner's Manual for recommended fuel filter replacement intervals.



DRAINING WATER FROM FUEL FILTER CANISTER:

The combination housing drain valve/WIF sensor (6) serves two purposes. One is to partially drain the filter housing of excess water. The other is to partially drain the housing for fuel temperature sensor, fuel filter or fuel heater element replacement.

The filter housing should be partially drained whenever the water-in-fuel warning lamp remains illuminated. (Note that lamp will be illuminated for approximately two seconds when ignition key is initially placed in ON position for a bulb check).


1. Raise and support vehicle.
2. A nipple is located at the bottom of drain valve (6). Attach a drain hose to this nipple. Place drain pan under drain hose.
3. With engine not running, Disconnect WIF sensor electrical connector (4) then rotate drain valve (6) approximately two revolutions to open it. Leave open until all water and contaminants have been removed and clean fuel exits. Hand tighten drain valve after tightening.
4. If fuel heater element is being replaced, drain housing completely. Dispose of mixture in drain pan according to applicable regulations.
5. After draining operation, close and tighten drain valve (6).


6. FUEL FILTER REPLACEMENT:
7. Remove left front tire/wheel.
8. Remove left front wheel splash shield.
9. Clean all debris from around filter canister (7) and canister head.
10. Open drain valve (6) two complete revolutions. Drain approximately 1 cup of fuel into a waste canister. Dispose of fuel according to environmental regulations.
11. Remove drain hose from drain valve (6).
12. Use an oil filter type wrench to loosen filter (7). Continue removing filter by hand.


13. WATER-IN-FUEL (WIF) SENSOR REPLACEMENT: The combination fuel drain valve/WIF sensor (6) is located on the bottom of the fuel filter housing.

The WIF sensor is not a separately serviceable item. If diagnostics have led you to replace this sensor, then the whole fuel filter assembly needs to be changed.




14. FUEL HEATER ELEMENT REPLACEMENT: The fuel heater element (1) is located in the fuel filter housing (8). To replace heater, the entire housing assembly must be replaced.
15. Drain fuel filter. See previous steps.


16. Disconnect electrical connectors (2), (3) and (4).


17. Disconnect two quick-connect fittings (1) and (2) at housing.
18. Remove three housing mounting nuts (3).
19. Remove housing assembly.


20. FUEL TEMPERATURE SENSOR REPLACEMENT: The fuel temperature sensor (5) is located in the fuel filter housing (8). To replace sensor, the entire housing assembly must be replaced.
21. Drain fuel filter. See previous steps.


22. Disconnect electrical connectors (2), (3) and (4).


23. Disconnect two quick-connect fittings (1) and (2) at housing.
24. Remove three housing mounting nuts (3).
25. Remove housing assembly.
26. DRAIN VALVE REPLACEMENT: The Drain Valve is located on the bottom of the fuel filter. This is not a separately serviceable item. If replacement is necessary, replace the entire filter/filter canister assembly.
