5. Test fit the stopper assembly into the
tank. It may be necessary to remove some of
the flashing around the tank opening using
amodeling knife. Ifflashing is present, make
sure none of it falls into the tank.
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 frontofthe tankshould justabout
touch the back of the firewall.
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.
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.

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
other end to the nylon pick up tube in the
stopper.

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.
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

and remove it.
3. Draw a center line onto the horizontal
stabilizer. Then slide the horizontal into the
fuselage.
