Install The Fuel Tank - GREAT PLANES Super Stearman Instruction Manual

13. Paint the engine flat black. After the paint dries install
the aluminum tubes and wire into the holes you drilled. On
the back of the engine apply a small amount of glue to each
wire and aluminum tube to hold them in place.
14. Place the dummy engine over the engine, and then
place the cowl over the dummy engine. Attach the cowl to
the fuselage with the four socket head cap screws and
washers. To position the dummy engine you will need two 9"
[229mm] balsa sticks and two small rubber bands (not
included). Loop a rubber band through a couple of the
aluminum tubes on one side of engine crankshaft. Insert the
stick through the rubber bands and place the stick onto the
front of the cowl. This will pull the dummy engine into the
front of the cowl. Repeat this with the second stick and
rubber band on the other side of the engine crankshaft.
15. Position the dummy engine so that the cut out is over the
engine cylinder and the hole you cut in the center of the dummy
engine is centered on the engine thrust washer. Be sure the
center cylinder on the dummy engine is centered at the top of
the fuselage. When you are satisfied with the positioning of the
dummy engine, carefully remove the cowl from the fuselage,
being careful not to disturb the dummy engine.
16. Using medium CA, tack-glue the dummy engine to the
cowl from inside the cowl. Re-install the cowl to the fuselage to
verify that the dummy engine is placed properly. When you are
satisfied with the way it fits, remove the cowl from the fuselage.
Permanently glue the dummy engine to the cowl from inside the
cowl with 6-minute epoxy mixed with microballoons.

Install the Fuel Tank

1. Assemble the fuel tank as shown in the sketch. When
tightening the center screw be sure not to over tighten it. You
just want it snug enough to pull the rubber stopper tight
against the tank.
2. Install the tank into the fuselage with the neck of the
tank through the firewall. The tank should fit snug enough to
stay in place during the construction process. The tank will
be permanently held in place when the battery/receiver tray
is installed later.
3. Install silicone fuel tubing onto the aluminum tubes
from the fuel tank. The line with the fuel clunk will feed to the
fuel inlet at the needle valve and the other will attach to the
pressure tap on the muffler. If you choose to use some kind
of an external fuel valve, follow the instructions with your
particular brand of fuel valve. You can also install a third line
to the tank and use it for filling the tank. The method you use
is your choice.
