Section 14 – Fuel Tank Assembly
Step 5
Slide the vent tube into one of the remaining two 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. 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. (
Hint
:
The fuel tank is taller than it is wide, with the stopper
located towards the top.) 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
have the clunk fall to the lowest point (all directions,
except for having the stopper facing down).
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.
Important
: Be sure to differentiate between
the vent and fuel pickup tube. Once the tank
is mounted inside the fuselage, it will be
difficult to tell the tubes apart.
