Fuel Filter: Procedures
WATER DRAINING AT FUEL FILTER HOUSING
The housing drain valve (4) serves two purposes. One is to partially drain the filter housing of excess water. The other is to drain the housing for fuel
filter or Water In Fuel (WIF) sensor replacement.
The filter housing (1) should be partially drained whenever the WIF 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 (6) is located at the bottom of drain valve. Place drain pan under drain hose.
2. With engine not running, Route the fuel drain hose to an appropriate container and rotate drain valve (4) one quarter turn counter clockwise to
open it. Also loosen the fuel filter housing cover a 1/2 turn and allow the fuel to drain from the fuel filter housing for two minutes. Rotate the drain
valve (4) clockwise one quarter turn to close it.
