I finished up th eplumbing of the Oxygen system today. I first needed to figure out a conduit for the copper high pressure O2 line in the overhead console. I made a trip to Ace hdwr. and found some 3' sections of very thin-walled aluminum tubing. I picked p two of those and a shorter section (12" ) of Brass tubung that had an ID of 1/4" to use as a coupling. I also picked up some poly tubing that I cut into 2" sections and slipped over the 'conduit' to keep it from rattling/chaffing in the overhead. I previously made an opening in the aft bulkhead and placed a snap bushing in it. I was able to insert the conduit from the tailcone into the snap bushing and forward until it projected into the opening in the Overhead console. (where the O2 dist manifold is). I secured the conduit and threaded the high pressure copper tubing through it. I left about 4 ' of tubing in the overhead close out area and couild it to make it easier to connect/disconnect the distribution manifold. then I figured out the routing and connections to connect to the Main bottle and to connect the bottle to the refill port. I left 5" service loops in each of these connections. Refilling is going to require an access door in the bulkhead (similar to Robin Marks) or remounting the refill valve to the aft bulkhead. The alternative is to completely remove the upholstery covering and the aft bulkhead for refill.
