I used the XRP XR-31 hose based on Best of Show's recommendation. I used a short piece from the fuel tank to a hard line and from the hard line at the firewall to the engine.
I just double checked the name and I see a disclaimer in the XRP catalog about the best hose for all fuel types being their PTFE lined HS-79 hose.
In 2 plus year and over 9k miles I havne't had a problem with my XR-31 hose and it is super easy to assemble.
For the connection at the fuel rail and the fuel pump I used the russel AN fitting with screw on retainer rather than the plastic retainer (like this:
