Section 12: 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 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.
Note
: The fuel tank will be installed in the next
section.
