1.5 hrs. on the brake lines.

I would have gone longer except that working inside the cockpit is quite fatiguing.  I'm not a tall guy (he says optimistically) and I have trouble being in there working for any length of time.  If you're taller/bigger than me (you probably are 😁) I suggest you do the brake and fuel lines before even putting on the side skins.  I did the electrical wiring before that, and I'm glad I did, but I wish I also had done the brake and fuel lines.

OK, here are my final parts.  From the top:

• 06-01137 (midway down the page Matco Part Number MSC268P)
• AN910 Coupling (1D Size)
• AN825 Tee (3D Size)
• AN816 Nipple, Flared Tube and Pipe Thread (3D Size) (2 of these)

UPDATE: Hold on these part selections as I might be rethinking things...  Also, probably shouldn't be using teflon tape...

I did a bunch of research and some plumbers say using teflon tape and Megaloc provides the absolute best leak free joint.  Can't hurt...

I tightened it pretty darn tight and thought I was done...

...But, using a longer wrench I was able to get it down all the way.

Putting the T in the vise I was able to more easily tighten the coupling into it.  A lot of torque required...

Better to do this outside the cockpit (like I said, minimize what you have to do in there...).

Hmm....  Tightening this part onto the Matco brake and well before it seemed to be sufficiently tightened, the part the wrench turns stripped...  It was the right size wrench and there wasn't any of the Megaloc on that area, so I'm not sure why the material stripped so easily.  Hmmm....
Advice?

I thought it would be a good idea to use some of the conduit I have to put the brake lines through.  This way if I ever need to replace the lines it will be easy to route through.  The floor over this area is riveted down, so I won't have easy access.
You can notice here that the walls of the center channel are warped.  I noticed this after I had put it on it's gear and kind of freaked.  But, I looked through factory photos and found some others had this same thing.  Not all though, so you may or may not see this.  Once the cover is on that channel, it won't be seen, so I don't care.

I did notice that screwing the brake lines onto the T they seemed to bottom out before reaching the end of the threads. It seems tight, but they got tight abruptly, not progressively like I'd expect it to be.  Normal?...

Well, assuming I don't need to take it back out because of the above noted "issue", then it's in place.  I understand that Bob wrapped his plastic line going forward to protect it, so I may do that too.
