Tonight, I began the installation of the Andair fuel selector. Since the plans do not cover the installation of an aftermarket Andair valve, this is one of those times when you just have to make everything work. Complicating the issue somewhat is the fact that I'm installing a Grand Rapids EIS unit just aft of the selector valve. (I don't want it on the main instrument panel -- I think it's sort of hideous-looking, and it's not required to be very accessible). After laying out the EIS mounting location, I proceeded to lay out the valve location.

I used a 4" x 5-1/2" sheet of 0.063" aluminum, supported by a length of 3/4" x 3/4" angle and the stock support angle, to actually mount the valve (See photos). Getting everything to fit just right, and also avoid conflicts with the pre-drilled holes in the mid-cabin cover, is a bit of a head-scratcher at times. It all came together, and the valve, support angles, and spacer plate are mostly ready to rivet and screw together when the time comes.
