o 3. Carefully bend the tubes that exit the stopper as shown.
Be sure that the lines do not have kinks at the bends. Attach
a gasoline compatible fuel line such as Tygon 6" [152mm] in
length to each of the two short tubes in the stopper. The long
tube (vent line) should be bent upward. Install the included
fuel clunks onto the fuel lines.

o 4. Insert the stopper into the tank and check the length of
the carb line and fill lines. The clunks should almost reach
the back of the tank when the stopper is in place but be able
to move around freely inside the tank. Adjust the length of
the fuel line until the proper length has been reached. The
vent line should almost reach the top of the tank. Once you
are satisfied with the fit, secure the stopper by tightening the
screw in the stopper assembly. Be careful not to over tighten
as the fuel tank could split.
o 5. Measure and mark 1/2" [13mm] from the front of the
firewall on the bottom of the motor mount box for the fill and
vent lines and drill a 1/4" [6.4mm] hole at your marks. Make a
mark on the firewall near the carburetor for the carb line and
drill another 1/4" [6.4mm] hole.
o 6. Attach approximately 10" [254mm] of gas compatible
fuel line to the fill line, carb line, and vent line.
o 7. Locate the gas fuel tank support pieces. Glue the
pieces together as shown. Be sure the sides of the pieces
are glued together flush. When complete, use epoxy to fuel
proof the two assembles.
