Section 11:
Assembling the Fuel Tank
Step 5. Slide the vent tube into one of the two remaining holes
in the stopper from the tank (small cap) side.
Step 6. Locate the short piece of silicone fuel tubing and the
fuel tank clunk. Install the clunk onto one end of the silicone
tubing and the other end onto the brass fuel tank pickup tube
(straight tube) in the stopper.

Step 7. Carefully insert the assembly into the fuel tank. Note the
position of the vent tube. It must be at the top portion of the fuel
tank to function properly. Also, it may be necessary to shorten
the length of the fuel pickup tubing to make sure the clunk does
not rub against the back of the fuel tank. You should be able to
turn the tank upside down, which allows the clunk to freely drop
to the top of the tank.
Step 8. Tighten the 3mm screw carefully — do not over tighten.
This allows the rubber stopper to form a seal by being slightly
compressed, thus sealing the fuel tank opening.
Important: Be sure to differentiate between the vent and
the fuel pick-up tube. Once the tank is mounted inside the
fuselage, it will be difficult to tell the tubes apart. We have
included two different color pieces of fuel tubing to help
you tell them apart. We suggest using the green tubing for
the fuel line to the carburetor of your engine and the red
tube for the vent tube.
Note: The fuel tank will be installed into the fuselage after
the engine mount is installed.
