Draining Fuel/Water Separator Filter
The fuel filter/water separator filter housing is located
above the rear axle next to the fuel tank. The best access
to this water drain valve is from under the vehicle.
CAUTION!
• Do not drain the fuel/water separator filters when
the engine is running.
• Diesel fuel will damage blacktop paving surfaces.
Drain the filters into an appropriate container.
If water is detected in the water separator while the
engine is running, or while the ignition switch is in the
ON 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.
