422 MAINTAINING YOUR VEHICLE Draining Fuel/Water Separator Filter (6.7L Diesel Engine) 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. CAUTION! Do not drain the fuel/water separator filter when the engine is running. 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.
