FUEL FILTER/WATER SEPARATOR — DIESEL ONLY
Draining Fuel/Water Separator
• If the "Water in Fuel" indicator light
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 Owner's Manual on the DVD for further details.
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.
• 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.
• 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.
