Ken,
I'm hoping to hear someday that your wife is getting better - it has to be a real downer for her. Just keep reminding her that some day in the near future it will be only like a bad dream.
Just looking at your fuel feed and return lines - I'm kinda surprised to see them running in the actual car body itself. You have done yours very much similar to mine with the stainless line, AN fittings and flex, but I chose to run mine along the frame. My impression is that I should keep them away from the inside of the car for collision/fire safety. I do have one area which might raise some eyebrows though as I have to cross my drive shaft ((it's a Ford with a mechanical fuel pump and it's opposite the normal right hand Chebbie)) though it is pretty well protected by a reinforced cross member/bracket and drive shaft loop.
