2. Insert four 6-32 blind nuts into the back of the fi rewall.
Use a 6-32 x 3/4" [19mm] SHCS and a #6 fl at washer to
draw the blind nuts tight into the fi rewall.

3. The fuel tank can be assembled as a two line system
consisting of a vent (pressure) line to the muffl er and a
carb line. Filling and emptying of the tank would need to be
done through the carb line, or an optional fuel fi ll valve (not
included). The tank can also be assembled as a three line
system having a vent line, carb line, and fi ll line. If installing
a fi ll line, puncture the top of the stopper above the sealed
off fuel tube hole. The fi ll and carb lines should extend out
1/2" [13mm] beyond the stopper and the vent line should be
bent upwards and left uncut. With the tubes installed in the
stopper, fi t the stopper plates loosely in place with the 3 x
25mm phillips screw to hold the assembly together.
❏
4. Fit the stopper assembly into the tank with the vent line
pointing toward the top of the tank, but not touching. The
fuel tubing and clunks (fuel pickup) on the carb and fi ll lines
should almost reach the back of the tank but not touch. The
clunks must be able to move freely inside the tank when
assembled. Adjust the length of the fuel tubing accordingly.
When satisfi ed, tighten the 3x25mm screw in the stopper to
secure it in place (do not over-tighten). Mark the side of the
tank that must face up when installed in the plane. We also
suggest marking the tubes in the stopper.

5. Cut a piece of 1/4" [6mm] thick foam rubber (not included)
to fi t the fuel tank and place it on the fuel tank tray. You may
fi nd it easier to insert the tank if you glue the foam to the tray.
