Hey Alex!

I run a Walbro 255 lph pump from inside the fuel cell to a 10 micron to 100 micon filters through PTFE lined -8AN stainless braided XRP crimped hose (close to 1/2") to a check valve at the firewall to a -8AN tee to my Fore Innovations billet fuel rails. I use an Aeromotive 13129 EFI regulator mounted with a -8 ORB fitting on the front passenger rail itself. Both fuel rails loop together in front and the return from the bottom of the regulator runs all the way back to the fuel cell.

There are XRP fittings available that convert hard line to AN, although they are only 50 psi maximum. That's why I went with full stainless braid for ease of installation.

Hope that helps!
