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.

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. Insert the tank into the fuselage with the correct
side facing up. The neck of the tank should pass
through the hole in the fi rewall. Attach a 6" to 7" [152
to 178mm] piece of fuel tubing onto each line coming
from the tank.

4. 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. Align the centering
mark on the engine mount with the lines on the fi rewall.
Slide the mount halves against the sides of the engine
and fi nish tightening the mount screws.
❏
5. Position the front of the engine drive washer
6-1/8" [156mm] from the fi rewall. Mark the location of
the engine mount holes onto the mount rails using a
Dead Center hole locator. Remove the engine from
the mount and use a 8-32 tap and drill set to create
