Draining water from fuel filter/water separator housing:
Fig.14 Water Drain Valve And Drain Hose
The housing drain valve (Fig. 14) serves two purposes. One is to partially drain filter housing of excess water. The other is to completely drain
housing for fuel filter, drain valve, heater element or water-in-fuel sensor replacement.
The filter housing should be partially drained whenever 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. A drain hose is located at bottom of drain valve (Fig. 14). Place drain pan under drain hose.
2. With engine not running, pull drain valve handle upward to OPEN (DRAIN) position (Fig. 14). Hold drain valve open until all water and
contaminants have been removed and clean fuel exits drain hose.
3. If drain valve, fuel heater element or Water-In- Fuel (WIF) sensor is being replaced, drain housing completely. Dispose of mixture in drain pan
according to applicable regulations.
4. After draining operation, push valve handle downward to CLOSE position (Fig. 14).
