INSTALLING THE STOPPER ASSEMBLY.

1) Using a modeling knife, carefully cut
off the rear portion of one of the 3 nylon tubes
leaving 1/2" protruding from the rear of the
stopper. This will be the fuel pick up tube.
2) Using a modeling knife, cut one length
of silicon fuel line. Connect one end of the line
to the weighted fuel pickup and the other end
to the nylon pick up tube.
3) Carefully bend the second nylon tube
up at a 45º angle. This tube is the vent tube.

Carefully use a lighter or heat gun to
permenently set the angle of the vent tube.
Important: When the stopper assembly is in-
stalled in the tank, the top of the vent tube
should rest just below the top surface of the
tank. It should not touch the top of the tank.
4) Test fit the stopper assembly into the
tank. It may be necessary to remove some of
the flashing around the tank opening using a
modeling knife. If flashing is present, make
sure none falls into the tank.
5) With the stopper assembly in place,
the weighted pickup should rest away from
the rear of the tank and move freely inside the
tank. The top of the vent tube should rest just
below the top of the tank. It should not touch
the top of the tank.
6) When satisfied with the alignment of
the stopper assembly tighten the 3mm x 20mm
machine screw until the rubber stopper ex-
pands and seals the tank opening. Do not
overtighten the assembly as this could cause
the tank to split.
