Section 11: Fuel Tank Assembly
Step 4
Locate the longer brass fuel tube and bend it as shown
using your fingers. This will be the fuel tank vent tube.
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.
