NGINE
The fuel/water separator filter housing is located
inside the frame rail, behind the left front wheel.
The best access to this water drain valve is from
under the vehicle.
If water is detected in the water separator while the
engine is running, or while the ignition switch is in
the ON/RUN position, the “Water In Fuel Indicator
Light” will illuminate and an audible chime will be
heard. At this point, you should stop the engine
and drain the water from the filter housing.

surfaces. Drain the filter into an appropriate
container.
