FUEL TANK.
INSTALLING THE STOPPER ASSEMBLY.
1. Using a modeling knife, carefully cut
off the rear portion of
one
of the two 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 (not included) to 2-1/4” long.
Connect one end of the line to the weighted
fuel pickup and the other end to the nylon
pickup tube.
3. Carefully bend the second nylon tube
up at a 45º angle. This tube is the vent tube.
4. Carefully heat the vent tube using a
heat gun or lighter to permanently set the
angle of the tube.

When the stopper assembly is installed 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.
5. 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.
6. With the stopper assembly in place,
the weighted pickup should rest about 3/8”
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.
7. 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.
