Section 9: Assembling the Fuel Tank
Step 6
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 ensure 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 7
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.
Step 8
Locate the two pieces of fuel tubing (red and green). Install the
red tubing onto the fuel pickup tube (the short strait tube) and
install the green tubing onto the tank vent tube (the bent tube
going to the top of the tank).
Step 9
Install the tank into the front of the fuselage with the fuel tubing
coming through the hole in the firewall.
Note: The tank will be secured in place after the radio
installation.
