Fuel Tank
1.
Collect the following item
(1) fuel tank 500cc (16.91 oz.)
(1) rubber tank stopper
(1) clunk
(1) 3mm x 25mm screw
(1) cap washer large
(1) cap washer small
(2) 3mm x 40mm brass tube
(1) 3mm x 60mm brass tube
(1) silicone tube 4mm x 80mm
(3) silicone tube 5mm x 165mm
2.
Insert the 3mm screw through the center hole
in the large washer, through the center hole in
the rubber washer against the large side, and
screw the small washer on the back side.
3.
Insert the brass tubes through three of the
holes. They should be arranged so as the long
one will be on the right side of the plane and
the short one on the left side.
The tubes should extend out the front of the
cap 5/8”. Bend the long tube up at about a 20
degree angle. This should be adjusted so the
end of the tube almost touches the top of the
tank when installed.
4.
Install the 4mm silicone tube to the short brass
tube and install the clunk to the other end of
the silicone tube. This is the fuel pickup and
must be free to “flop” around in the tank so it
can pick up fuel in any attitude.
5.
Install the assembly into the tank so the vent
tube is turned up to the top of the tank and is
positioned on the right side of the tank. Tighten
the screw to expand the rubber cap. Don’t over
tighten or you could split the tank.

5.
Attach the three pieces of 5mm tubing to the
three tank outlets. They are different colors so
you can tell which are the two vents and which
is the fuel pickup after the tank is installed.
Make a note of which color you attach to which
tube. The short brass with the clunk is the fuel
pickup and must go to the carburetor. One of
the long brass tubes is the vent and should go
to the pressure outlet on the muffler. The sec-
ond vent can be used for filling the fuel tank but
will have to be plugged with a screw (Not
Included) so that the fuel will not run out.
