3. Slide the plastic cap over the tubing at the front. Start
the M3 x 20 machine screw using a #1 Phillips screwdriver.
The screw only needs to be in far enough to keep the large
stopper plate from falling off.
4. Use solder and a soldering iron to create a small barb
for the fuel line. This is necessary as the tubing will need to
be wired on to prevent it from sliding loose.
5. Slide the fuel tubing on the straight piece of brass
tubing. The clunk will be placed on the opposite end of the
fuel tubing.
6. Insert the stopper assembly into the fuel tank. Make
sure the vent line faces to the top of the tank as shown.
Check to make sure the clunk can move freely inside the
tank. If not, trim the length of the tubing as necessary so it
can move and is as close to the end of the tank as possible.
Once the length of the tubing is set, remove the assembly
from the tank. Use a piece of small music wire to secure
the line to the clunk and the brass tubing. If the tubing is
not wired on, the oils in the fuel will decrease the friction fit
between them and they will slide free.
7. Place the stopper back in the tank. Use a #1 Phillips
screwdriver to tighten the M3 x 20 machine screw to secure
the stopper. Don’t over-tighten the screw as you could
damage the fuel tank. It needs to be tight enough to create
a seal between the tank and stopper. Slide the fuel tubing
onto the brass tubes outside the tank. Make sure to wire the
tubing to the brass tubes so it will remain attached during
the operation of your model.
8. Wrap the ignition battery in 1/4-inch (6mm) foam
and place it inside the fuselage. Add wrapped 1/4-inch
(6mm) foam to keep the battery from moving inside the
fuselage when the fuel tank is installed. Route the lead to
the switch harness. Connect the leads and secure them
using dental floss or string. We also recommend using a
balancer extension and securing it to the fuselage using a tie
wrap (not included) so the battery can be charged without
removing the fuel tank.
