INSTALLING THE FUEL TANK.
1)
The stopper has been pre-assembled at the
factory.
2)
Using a modeling knife, cut one length of silicon
fuel line (the length of silicon fuel line is calculated by
how the weighted clunk should rest about 8mm away
from the rear of the tank and move freely inside the
tank). Connect one end of the line to the weighted
clunk and the other end to the nylon pick up tube in
the stopper.
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.
4)
Carefully bend the third nylon tube down at a 45
degree angle (using a cigarette lighter). This tube
will be vent tube to the fueling valve.
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 of it falls into 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.
Connect 2 lines to the 2 vent tubes and 1 line to the
fuel pickup tube in the stopper.
8)
Feed three lines through the fuel tank
compartment and through the pre-drilled hole in the
firewall. Pull the lines out from behind the engine,
while guiding the fuel tank into place. Push the fuel
tank as far forward as possible, the front of the tank
should just about touch the back of the firewall.
Blow through one of the lines to ensure the fuel lines
have not become kinked inside the fuel tank
compartment. Air should flow through easily.
Do not secure the tank into place permanently
until after balancing the airplane. You may need to
remove the tank to mount the battery in the fuel tank
compartment.
9. Secure the fuel tank.
