Just looking for opinions. I'm going go be running a new fuel line in my truck. Was going to use the 8an braided line i have from my Duster (because it's free and its not currently doing anything), but now am having second thoughts because I have 6an ends on the tank and the fuel rail and would have to jump up on both ends.

So the other options I'm considering are 3/8" hard steel line or 3/8" hard aluminum line. I plan on running E85, I'm assuming that won't bother either of the hard lines, right? I like the idea of aluminum because it's soft and easier to work with, and i could just get one long length of it (no joints, less places to leak).

So what do you guys think? Free 8an, aluminum 3/8", or steel 3/8"?
