Installation Location
The Fuel Pro must be installed between the fuel tank and
the fuel transfer pump . In some cases, the Fuel Pro can be
used as the only fuel filter in the system . This is generally
dependent on the engine model year . Consult the engine
manufacturer for their recommendation .
Mounting the Fuel Pro
• Do not install the Fuel Pro directly on the engine .
• Mount vertically with the cover and element pointing
up .
• Make sure there is enough top and side clearance for
the cover to be conveniently removed for filter replace-
ment .
• The Fuel Pro MUST be installed so that the filter ele-
ment is above the "FULL" level of the fuel tank .
� The ignition key must be in the off position, unless
otherwise directed. To avoid unintentional engine
startup, use a lockout key and/or signage to alert
personnel that work is being performed. Chock the
wheels.
1 . With the engine shut down and at ambient temperature,
close the fuel shutoff valve (if equipped) and place a
suitable container under the fuel filters .
2 . Remove the primary fuel filter element assembly, sedi-
menter, and/or water separator . Drain the used element
and dispose of it in an environmentally responsible
manner, according to state and/or federal (EPA) recom-
mendations .
Fuel Line Routing
To minimize fuel system restriction, observe the follow-
ing guidelines when plumbing the fuel system:
• Keep the fuel line routing as smooth as possible with
no low-hanging loops which can trap water .
• Use 90° elbows only when necessary .
• If the fuel hoses are cut to length on the job, be sure
that the inner liner of the fuel hose is not cut by the fit-
ting, which can cause check valve performance issues .
Make sure hoses are clean and free of debris before
installing .
• To avoid damaging the aluminum Fuel Pro body, do not
overtighten fuel lines or fuel linåe fittings .
3 . Route the fuel supply line from the pick up on the fuel
tank to the Fuel Pro inlet (labeled “FUEL IN” on figure
below, not labeled on housing) .
4 . Route the fuel outlet line from the Fuel Pro outlet (la-
beled “FUEL OUT”) to the inlet of the fuel pump .

Out configuration . Fuel In is also available on the right side .
