2. 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 3 x 25mm screw in the stopper to
secure it in place (do not overtighten). Mark the side of the
tank that must face up when installed in the plane, and we
also suggest marking the tubes in the stopper.

3. Make two 12" [305mm] long hook and loop straps from
the included hook and loop material by overlapping the mating
ends of each side by approximately 2" [51mm]. Insert the
straps into the slots in the plywood fuel tank tray as shown.

4. Fit the fuel tank tray into the fuselage by inserting the tab
at the forward end of the tray into the slot in the fi rewall. Press
the tray down onto the receiving tabs in the fuselage former
and cross brace. Drill two 1/16" [1.6mm] holes through the
tray and into the hardwood mounting blocks. Secure the tray
in place using two #2 x 1/2" [13mm] screws and two #2 fl at
washers, being sure to harden the screw holes with thin CA.

5. Cut a piece of 1/4" [6mm] foam rubber (not included) to
fi t the fuel tank. Lay the foam rubber onto the fuel tank tray (it
can be glued into place). Insert the neck of the tank through
the hole in the fi rewall as far as it will go (being sure that the
right side of the tank is facing up). Use the hook and loop
straps to secure the tank in place.

6. Attach a 6" [152mm] piece of fuel tubing to each of the
tubes in the fuel tank stopper.

7. Using four 6-32 x 3/4" [19mm] SHCS, four #6 fl at
washers, four #6 lock washers, and threadlocking compound,
attach the engine mount side-mounted to the fi rewall so that
