3. Open the drain valve at the base of
the fuel processor, and drain the fuel
until it is below the level of the filter.
Close the drain valve. The fuel may be
returned to the tank.
4. Using filter collar wrench 23516731 or
equivalent, remove the collar by turn-
ing counter-clockwise. Remove the
cover, filter spring, and cover seal ring
by lifting straight up and over the filter
element. Remove the element from
the center stud (fuel outlet pipe) by
pulling upward and twisting slightly.
NOTE:
Current filter elements include an integral
sealing grommet. Former filter elements
used a separate sealing grommet. If a
former element is replaced, make sure
the separate sealing grommet is
removed from the center stud.
5. Dispose of the used filter element and
grommet in an environmentally
responsible manner, according to
state and/or federal (EPA) recommen-
dations.
6. Check to make sure a sealing grom-
met is included in the base of the
replacement element, then install the
element onto the center stud.
7. Check to make sure the filter spring is
installed at the top of the cover. If
missing, this spring must be replaced
to insure proper filter operation. Wipe
the cover lip and cover seal clean.
After making sure the seal is properly
positioned at the base of the cover,
install the cover and collar onto the
fuel processor. Tighten the collar by
hand until secure.
NOTICE:
Do not use a wrench of any kind to
tighten the collar, since this may lead
to overtightening which can damage
the collar and/or the cover.
8. Remove the vent plug from the top of
the cover by turning the plug counter-
clockwise. Fill the cover full of clean
fuel. After making sure the O-ring seal
is installed on the vent plug, reinstall
the plug and tighten by hand only.
NOTICE:
To avoid cover or vent plug damage,
do not use tools to tighten the vent
plug.
9. Open the fuel shutoff valve (if installed)
and start the engine. When the lubri-
cation system reaches its normal
operating pressure, increase engine
speed to high idle for 2 to 3 minutes.
NOTICE:
Do not allow the fuel level in the see-
through cover to fall below the top of
the collar, since this may lead to inter-
ruption of the fuel flow and engine
stalling.
10. After the air is purged and with the
engine still running, loosen the vent
cap. The fuel level in the cover will
start falling. When the fuel level falls
to the top of the collar, tighten the
vent cap quickly by hand.
11. Shut down the engine and hand
tighten the collar again.
