at the factory.
2) Using a modeling knife, cut one length of
siliconfuel line (thelength ofsilicon fuelline is
calculated by how the weighted clunk should
restabout 8mmaway fromthe rearof thetank
andmove freelyinside thetank). Connectone
end of the line to the weighted clunk and the

3) Carefully bend the second nylon tube up at
a 45 degree angle (using a cigarette lighter).
This tube will be the vent tube to the muffler.

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 of it falls into the tank.
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.

6) When satisfied with the alignment of the
stopper assembly tighten the 3mm x 20mm
machine screw until the rubber stopper
expands and seals the tank opening. Do not
over tighten the assembly as this could cause
the tank to split.
7) Using a modeling knife, cut 3 lengths of
fuel line 150mm long. Connect 2 lines to the 2
vent tubes and 1 line to the fuel pickup tube in
the stopper.
Blow through one of the lines to ensure
the fuel lines have not become kinked inside
the fuel tank compartment. Air should flow
througheasily.
9) To secure the fuel tank in place, apply a
bead of silicon sealer to the forward area of
thetank, whereitexitsthefuselage behindthe

Do not secure the tank into place perma-
nently until after balancing the airplane.
You may need to remove the tank to mount
