ENGINE MOUNTED FUEL FILTER/WATER SEPARATOR
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/RUN 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 Diesel Supplement on the DVD for further details.
Fuel Filter Replacement
• 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 N·m). Do not
overtighten the lid.
• Start the engine and confirm no leaks are present.
The engine mounted filter housing is equipped with a No-Filter-No-Run (NFNR)
feature. Engine will not run if:
1. No filter is installed.
2. Inferior/Non-approved filter is used. Use of OEM filter is required to ensure
vehicle will run.
