ment 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)
counterclockwise 1/4 turn, and turn the
under body mounted filter drain valve
(located on the bottom of the filter assembly)
counterclockwise wise 1 full turn. Then turn
the ignition switch to the ON position, and
allow any accumulated water to drain. Leave
the drain valve open until all water and
contaminants have been removed. When
clean fuel is visible, close the drain valve
following these guidelines:
1. Rotate the drain clockwise to close until
you feel resistance from the internal seal.
2. Continue turning the drain 1/2 of a turn
to properly compress the seal.
NOTE:
Over-compression of the seal due to
over-tightening of the drain will damage the
seal, cause a leak, and require the entire
sensor to be replaced.
3. Turn the ignition switch to OFF.
The sensor drain should not be over-tight
-
ened during normal service operations to
avoid internal damage and future fuel leaks.
The drain should be close and secured
without the use of tools.
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 sepa
-
rating 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:
a. No filter is installed.
b. Inferior/Non-approved filter is used.
Use of OEM filter is required to ensure
vehicle will run.
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
removal. Remove used o-ring and discard
it.
CAUTION!
Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appro
-
priate 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.
