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.

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 over tighten). 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. Attach a 6"-7" [152mm-178mm] piece of fuel
tubing onto each line coming from the tank. Insert the
tank into the fuselage with the correct side facing up.
The neck of the tank should fi t into the former behind
the fi rewall. We recommend marking the fuel lines so
they can be easily identifi ed when connecting them to
the engine.

4. Install the plywood throttle servo tray behind
the fuel tank using four #2 x 3/8" [9.5mm] self-tapping
screws and four #2 fl at washers. The tray should be
pressed up against the back of the fuel tank to prevent
it from moving in fl ight.
❏
5. Using four 8-32 x 1" [25mm] SHCS, four #8 fl at
washers, four #8 lock washers, and threadlocking
compound, attach the engine mount inverted to the
fi rewall. Leave the screws slightly loose. Test fi t your
engine between the mount halves. Slide the mount
halves against the sides of the engine and fi nish
tightening the mount screws.
