Section 11: Fuel Tank Assembly
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. Slide the silicone tubing (end
opposite the clunk) onto the fuel tank pickup tube
(straight tube) in the stopper.
Step 7
Carefully insert the stopper assembly into the fuel
tank. Note the position of the vent tube; it must be up
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 to any attitude, and the clunk will
fall to the lowest point. (All directions except for
having the stopper facing down.)
Note
: The fuel tank is taller than it is wide.
Step 8
Tighten the M3 x 20 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.
Step 9
Mark the vent tube on the fuel tank. This will
be helpful after the tank has been mounted in
the fuselage.
