138. Test fit the fuel tank and adjusts the velcro strap installed at the

factory. Keep trying until the strap is a nice tight fit when you slide the
tank in.

139. Slide the tank into place. Make sure it is square and butted against the

former behind it. Use some silicone glue for extra security. Silicone
keeps the tank in place, but still leaves it easy to remove in case service
is needed.

140. Adjust the size of the hole in the radio tray to fit your UAT or header

tank. A sharp Exacto with a new blade will cut the plywood very
accurately with a few strokes.
