-inch (38mm) piece of red airline. Attach the
air line to the retract fill valve. The fill valve is the

the portion that will orient towards the inside of
the wing. Do not confuse this valve with the quick-
disconnect valve that is also included.

The hex on the fill valve will key into the hex in the
plastic. The top of the fill valve will be flush with the
plastic on the inside of the wing. Connect a T fitting
to the end of the red air line connected to the fill
valve. Connect the red air line from the retract valve
to the this T-fitting as well. This may need to be
trimmed slightly.
Always use threadlock on metal-to-metal fasteners
to prevent them from vibrating loose.
9. Use a hobby knife with a #11 blade to trim a
2-inch (52mm) piece of red airline. Connect the
airline to the quick disconnect valve. Connect the
opposite end of the air line to a t-fitting.
