following: Draining Water from Filter.
DRAINING WATEE FROM FILTER; The filter
should be drained whenever the water-in-fuel warn­
ing lamp remains illuminated. (Note that the lamp
will be illuminated for approximately two seconds
when the ignition key is initially placed in the ON
position for a bulb check). The drain valve can also
be used to drain excess fuel from the filter when
replacement of the filter is necessary.

the bottom of the water-in-fuel (WIF) sensor (Fig.
71). Place a drain pan under the drain hose. With
the engine not running, push up on the drain
valve (Fig. 71) to remove the water from the filter/
separator. Hold the drain valve open until all water
and contaminants have been removed and clean fuel
exits the drain. Dispose of mixture in drain pan
according to applicable regulations.
(2) Remove the drain hose at the drain valve (Fig.
