Same here. All aluminum under the car, I would NEVER run rubber under the car. Too many risks of puncture and weathering. Ran the 3/8" hardline up through between the firewall and the sub-frame?? assembly was a bitch and a half. Then SS lines to and from the engine to avoid any damage from vibration and engine movement...





It sucked trying to get them through there without ruining them.

Anyway I used to run a 5/16" steel return line and it worked just fine. It went from the return port on the bottom of the SFMU down and under the car and back to the tank where it used rubber hoses to attach to the stock return port.
