
5. Slide an aluminum tube through the stopper. Position
the front of the tube even with the bent tube as shown.

6. Slide the larger stopper plate over the tubing at
the front. Start the M3 x 20 screw using a #1 Phillips
screwdriver. The screw only needs to be in far enough to
keep the large stopper plate from falling off. Slide the fuel
tubing on the straight piece of aluminum tubing. The clunk
will be placed on the opposite end of the fuel tubing.

If you are assembling the fuel tank for use with a
gas engine, you will need to use solder and a soldering
iron to create a small barb for the fuel lines before
they are installed. This is necessary as the tubing will
need to be wired on to prevent it from sliding loose.

7. Insert the stopper assembly into the fuel tank. Make
sure the vent line faces the top of the tank as shown.

8. Use a #1 Phillips screwdriver to tighten the M3 x 20
screw that secures the stopper in the tank. Don't over-tighten
the screw as you could damage the fuel tank. It needs to be
tight enough to create a seal between the tank and stopper.
Slide the fuel tubing on the tubes outside the tank.

We recommend using red and green fuel lines
for your model. Slide the red line on the vent line
and the green line on the line from the clunk.

If you will be using a gas engine, secure the
fuel line to the tubes so they don't slip off in
flight by using a small wireitie or safety wire.

9. Use medium CA to glue the four plywood hooks in
the slots inside the fuselage. The hooks are installed by
inserting them at an angle through the slots, then rotating
them into position.
