Ok guys I can understand the concern with fatigue in a vibrating section, but even a stainless steel braided line will at best have a teflon inner tube. That is good to about 325 degrees. Aluminium melts at what, about 1200-1300 degrees. If you do use aluminium tubing use the soft annealed stuff and use a flare or compression fitting on the ends. How well you finish the install would probably be more important than the material.

Yeah, I try to avoid rubber fuel lines too. Stainless braid, silicone,
fire-sleeved line; call me picky.

And hopefully your firewall is not plastic...!
