FUEL TANK
FUEL TANK ASSEMBLY
o
{1} Molded Fuel Tank
o
{1} Rubber Stopper
o
{1} 20mm Diameter Front Squash Plate
o
{1} 18mm Diameter Rear Squash Plate
o
{1} 3mm x 20mm Machine Screw
o
{1} Weighted Metal Pick-Up
o
{3} Aluminum Tubes
o
{1} 70mm Silicon Fuel Tube
o
1) The fuel tank assembly incudes 3 differ-
ent length aluminum tubes. Discard the shortest
of the three. It will not be used.
The 40mm length tube is used for the fuel
line pickup and the 70mm tube is used for
the vent/pressure line.
o
2) Using 220 grit sandpaper carefully
smooth each end of the two tubes. This will pre-
vent the fuel line from being cut.
o
3) Push the two aluminum tubes through the
rubber stopper until 1/2” protrudes from the front
of the stopper. Slide the 20mm diameter front
squash plate over the tubes at the front of the
stopper and slide the 18mm diameter rear squash
plate over the tubes at the rear of the stopper.
Insert the 3mm x 20mm machine screw into the
center hole in the front squash plate, then screw it
through the stopper and into the rear squash plate.
Do not completely tighten the screw at this time.

6) Test fit the stopper assembly into the tank.
It may be necessary to remove some of the plas-
tic flashing around the tank opening using a mod-
eling knife. If flashing is present, make sure none
falls into the tank when you remove it.
o
7) With the stopper assembly in place the
weighted pickup should be about 3/8” away from
the rear of the tank and move freely inside the
tank. The vent tube should be just below the top
of the tank, but not rub against the tank. Adjust
the tubes accordingly.
o
8) When satisfied with the alignment of the
stopper assembly tighten the 3mm x 20mm ma-
chine screw until the rubber stopper expands and
seals the tank opening. Do not overtighten the
assembly as this could cause the tank to split.
FUEL TANK INSTALLATION
o
9) Slide the fuel tank into the fuel tank com-
partment in the front of the airplane. The top of
the tank should face the top of the fuselage and
the stopper assembly should also engage the pre-
drilled hole in the firewall.
o
5) Secure the nose skid in place by install-
ing the six 3mm x 12mm wood screws through
the mounting straps and remove the masking tape.
See photo # 28 below.

o
4) Carefully bend the longer of the two tubes
up at a 45º angle. This tube is the vent tube.
When the stopper assembly is installed in the tank,
the top of the vent tube should rest just below the
top of the tank.
You can determine the top of the tank by
looking at the front of it. Notice that the
hole in the front of the tank is not centered. The
tall side is the top of the tank.
o
5) Slide the silicon fuel tubing, with the
weighted pickup attached to one end, onto the
fuel pickup tube. See photo # 29 below.
