Anyone replaced their fuel lines with bigger stainless ones?

I haven't done this but from what I understand if you wanted to use stainless braided fuel lines then you want something that is PTFE lined. That will ensure it doesn't deteriorate from the inside out. As far as manufacture goes I would use one of the big names but just as important is to use quality fittings. I hope this helps a little bit.

I'm talking about the hard lines. Just bigger diameter and made of stainless. For the flex part that goes to fuel rails and to the pump module I'll use PTFE lined flex hoses.

Here you go. http://www.speedymetals.com/pc-4469-...-annealed.aspx
Really any seamless wall tubing will do. The link is for 1/2" tubing, really no need for anything bigger then that. But if you do they offer 5/8" as well.

No need to go crazy on it the fuel pressure is nothing compared to what these lines are rated to handle. For example the .0035 wall tubing has a working pressure of 2,625psi and a burst pressure of 10,500psi. So no worries with your 58psi fuel pressure. lol. I wouldn't worry just find a decent price SS seamless and go with it.

I think people go way overboard with wall thickness on the SS hard lines. The first line I bought was standard .035 wall. It was a bastard to work with and impossible to flare with a hand tool.
I now use .020 wall hard line from brewing companies. Pretty easy to bend and can be flared with hand tools and a little heat. I've used this on may builds with 80+psi of fuel presure. Works great and is cheap.
I used standard AN nuts/collars/fittings
Max. Pressure (PSI) 1678 psi @ 72°F
Temp. Range: -325° to 1500°F
