position, there may be a problem with your
water separator wiring or sensor. See your
authorized dealer for service.
Upon proper draining of the water from both
fuel filters, the "Water In Fuel Indicator
Light" will remain illuminated for approxi-
mately 10 seconds. If the water was drained
while the engine was running, the "Water In
Fuel Indicator Light" may remain on for ap-
proximately three minutes.
NOTE:
Care should be taken in disposing of used
fluids from your vehicle. Used fluids, indis-
criminately discarded, can present a problem
to the environment. Contact an authorized
dealer, service station, or government agency
for advice on recycling programs and for
where used fluids and filters can be properly
disposed of in your area.
Drain the fuel/water separator filters when
the "Water In Fuel Indicator Light" is ON.
Within 10 minutes of vehicle shutdown, turn
the engine mounted filter drain valve (located
on the side of the filter assembly) counter-
clockwise 1/4 turn, and turn the under body
mounted filter drain valve (located on the
188
bottom of the filter assembly) counterclock
wise 1 full turn. Then turn the ignition switch
to the ON position, and allow any accumu-
lated water to drain. Leave the drain valve
open until all water and contaminants have
been removed. When clean fuel is visible,
close the drain valves by turning them fully
clockwise, and turn the ignition switch to
OFF.
If more than a couple ounces/milliliters of
fuel have been drained, follow the directions
for "Priming If The Engine Has Run Out Of
Fuel."
Engine Mounted Fuel Filter
Replacement
NOTE:
• Using a fuel filter that does not meet the
manufacturer's filtration and water separat-
ing requirements can severely impact fuel
system life and reliability.
• 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.
CAUTION!
• Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appro-
priate container.
• Do not prefill the fuel filter when install-
ing 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.
1. Ensure engine is turned off.
2. Place drain pan under the fuel filter drain
hose.
3. Open the water drain valve 1/4 turn coun-
terclockwise and completely drain fuel
and water into the approved container.
4. Close the water drain valve.
5. Remove lid using a socket or strap
wrench. Rotate counterclockwise for re-
moval. Remove used o-ring and discard it.
