Filter Change Procedure
E WARNING:
Fuels are combusible.
• RISK OF FIRE OR EXPLOSION:
• Avoid open flames, electrical sparks or igni-
tion sources
Note: Do not smoke. Change the filter only when the fuel
level reaches and remains at the top of the black band on
the filter. The filter may become dark, however, there is
additional filter capacity and restriction will remain low until
the fuel reaches the black band.
1. Turn off the engine. Remove the vent cap and dispose
of the O-ring. Clean the threads of the vent cap and on
the top of the cover. Set the vent cap aside.
2. Open the drain valve and drain the fuel completely
from the unit, then close the drain valve. The unit must
be completely drained to prevent contamination of the
clean side of the filtration system.
3. Using the collar wrench loosen the collar. (See Figure
13) Remove the clear cover and collar from the Indus-
trial Pro. Discard the cover O-ring and install a new
O-ring (supplied with the filter) on the cover. Clean the
threads on the collar and body of the Industrial Pro.

4. Install the new O-ring on the vent cap (supplied with
the filter).
5. Remove the filter element(s) from the Industrial Pro by
pulling upward.
6. Install the new filter element. Figure 14 shows a key of
the filter which fits into a keyway on the center boss.
Position the filter element so the filter element key is
lined up with the keyway on the center boss of the
housing and press the filter element into the housing.
Ensure the filter element is fully seated by firmly push-
ing on the end plate.

7. After checking to make sure the new o-ring seal is
seated correctly on the base of the cover, install the
cover and collar. Simultaneously apply modest pres-
sure to the top of the cover and turn the collar until it
no longer spins freely. Using the collar wrench, tighten
the collar the distance of two additional ribs.
8. Prime the fuel system according to the steps in the
"Priming the Fuel System" section in this manual. (The
vent cap will be returned to the Industrial Pro during
the priming process).
Priming the Fuel System
1. Check to make sure the drain valve at the base of the
Industrial Pro is closed. Close the fuel shutoff valve (if
equipped).
2. Remove the vent cap from the top of the clear cover.
Fill the Industrial Pro full of clean fuel. Tighten the vent
cap
(tighten by hand only)
until it “clicks”.
3. Open the fuel shutoff valve (if equipped). Start the en-
gine. When the lubrication system reaches its normal
operating pressure, increase engine speed to high idle
for one to two minutes. Loosen the vent cap until the
fuel level drops to just above the collar. Tighten the
vent cap (tighten by hand only) until it “clicks”.
Note: The clear filter cover will not fill completely during
engine operation. It will gradually fill over time and the fuel
level will rise as the filter becomes clogged.
