Draining Fuel/Water Separator Filter (6.7L Diesel Engine) - Dodge 2008 DH Ram Owner's Manual

422 MAINTAINING YOUR VEHICLE
Draining Fuel/Water Separator Filter (6.7L Diesel
Engine)
CAUTION!
Do not drain the fuel/water separator filter when the
engine is running.
CAUTION!
Do not prefill the fuel filter when installing a new
fuel filter. There is a possibility that debris could be
introduced into the fuel filter during this action. It is
best to install the filter dry and allow the in-tank lift
pump to prime the fuel system.
NOTE: The fuel filter and water separator assembly is
located on the driver's side of the engine. The best access
to the water drain valve is through the driver's side
wheel well.
NOTE: If water is detected in the water separator while
the engine is running or while the key is in the on
position, the WATER IN FUEL LIGHT will illuminate
and an audible chime will be heard five times. At this
point you should stop the engine and drain the water
from the separator.
