MAINTAINING YOUR VEHICLE FUEL FILTER/WATER SEPARATOR - DIESEL ONLY Draining Fuel/Water Separator • If the "Water in Fuel" indicator light is illuminated and an audible chime is heard five times, you should stop the engine and drain the water from the separator. • The drain is located on the bottom of the Fuel Filter and Water Separator assembly which is located on the driver's side of the engine. • Turn the drain valve (located on the side of the filter) counterclockwise 1/4 turn, then turn the ignition switch to the ON position to allow any accumulated water to drain. • When clean fuel is visible, close the drain and switch the ignition to OFF. • Refer to the Owner's Manual on the DVD for further details. CAUTION! • If the "Water In Fuel Indicator Light" remains on, DO NOT START the engine before you drain water from the fuel filter to avoid engine damage. • Do not drain the fuel/water separator filter when the engine is running. • Diesel fuel will damage blacktop paving surfaces. Drain the filter into an appropriate container. Fuel Filter Replacement - Diesel Only • With the engine off and a drain pan under the fuel filter drain hose, open the water drain valve 1/4 turn counterclockwise and completely drain fuel and water into the approved container. • Close the water drain valve and remove the lid using a socket or strap wrench; rotate counterclockwise for removal. Remove the used o-ring and discard it. • Remove the used filter cartridge from the housing and dispose of according to your local regulations. • Wipe clean the sealing surfaces of the lid and housing and install the new o-ring into ring groove on the filter housing and lubricate with clean engine oil. • Install a new filter in the housing. Push down on the cartridge to ensure it is properly seated. Do not pre-fill the filter housing with fuel. • Install the lid onto the housing and tighten to 22.5 ft lbs (30.5 Nm). Do not overtighten the lid. • Start the engine and confirm no leaks are present. CAUTION! • Diesel fuel will damage blacktop paving surfaces. Drain the filter into an appropriate container. • Do not prefill the fuel filter when installing a new fuel filter. There is a possibility 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. 72
