NOTE: Broken vent cap and collar warranty
claims will not be accepted if any tool other than
a DAVCO collar wrench, p/n 380134 or 382002,
is used for removal. During installation, the vent
cap and collar are to be
hand-tightened only ,
not tightened with a wrench.
5. Remove the filter and dispose of it in an environ-
mentally acceptable manner.
6. Clean all threads and sealing surfaces very thor-
oughly. Even a small amount of dirt will prevent
the fuel/water separator from sealing, and an air
leak will result.
7.
Ensure that the drain valve is closed.
8. Remove the filter grommet from the filter stud, if
equipped.
9. Fill the housing to the top with clean diesel fuel.
10. Install a standard fuel filter element on the filter
stud. If a standard filter element is not available,
install a spin-on fuel filter element (part number
FF105 or equivalent).
11. Install the cover O-ring, clear cover, and the col-
lar. Hand-tighten the collar.
12. Install and hand-tighten the vent cap O-ring and
vent cap.
13. Start the engine. When the lubricating oil
reaches its normal operating pressure, increase
engine speed to high idle for one to two minutes
to purge air from the system.

WARNING
Batteries release explosive gas. Do not smoke
when working around batteries. Put out all flames
and remove all sources of sparks or intense heat
in the vicinity of the battery. Do not allow the ve-
hicles to touch each other. Do not lean over the
batteries when making connections, and keep all
other persons away from the batteries. Failure to
follow these precautions could lead to severe
personal injury as a result of an explosion or
acid burns.
NOTICE
Make sure both electrical systems are the same
voltage. Electronic devices on both vehicles can
be damaged when connected to a vehicle with a
different operating voltage.
1. Apply the parking brakes and turn off all lights
and other electrical devices. Ensure that the ve-
hicles are not touching and both ignition switches
are turned to the OFF position.
