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
150mm long. 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.
9)
To secure the fuel tank in place, apply a bead of
silicon sealer to the forward area of the tank, where it
exits the fuselage behind the engine mounting box and
to the rear of the tank at the forward bulkhead.
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.

ENGINE INSTALLATION
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.
