trial Pro inlet (see Figure 2). Route a fuel line from the
Industrial Pro outlet to the fuel pump inlet.

CAUTION: To avoid fuel line water traps that can freeze
in cold conditions and restrict, or block, the flow of
fuel to the engine, be certain that there are no low
spots in the hoses when routing them in the engine
compartment.

Note: When the engine is shut off, fuel levels may drop
until the engine is restarted.
To minimize restrictions, observe the following guidelines
when plumbing the 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 made up to length on the
job, be sure that the inner liner of the fuel hose
is not cut by the fitting, creating potential check
valve effects. Also make sure hoses are clean
and free of debris before installing.
E CAUTION: To avoid damaging the aluminum fuel
housing, do not over-tighten fuel lines or line fittings.
Do not exceed 65 ft-lbs (88 N∙m). See the table of
torque values on page 10.
7. Apply liquid thread sealant to the inlet and outlet hose
threads and connect the hoses to the unit.
