John,

 

1. The blue/green tubing is the low pressure oxygen supply piped to outlets at either side of the rear seat and to the sides of the instrument panel.

 

2. Yes, theses are supports for the side panels.

 

3. I using two batteries, and two alternators, but only one main buss.  I have a separate relay for each battery and also a crosstie.

 

4. I haven’t worked on that yet. There really is no way to connect a scat tube to the slots in the engine compartment without making an alum or FG fitting to fit the valve.  If    I come up with an idea, I’ll pass it along.

 

5. I’m not actually installing a “hat rack” per se.  I installed a small shelf up high behind the reinforcing flange to hold magnetometers, if I go that route. The reinforcing flange is now supposed to be structural, I believe.
