I used 5/16" steel fuel line from O'reilly and bent my own up, ran them up against the inside of the frame rail all the way to the front and it worked great.
That sucks about your expensive stainless!
Ya, with my car it was issues with the Dougs headers being so close. So I decided flex line was easier to bend and buckle to the frame rails. Not to mention I think I suck at doing the plumbing stuff....
