Fuel line sizing

[Viper in a Rolls]

I am putting a 2004 Viper engine in my 1930 Rolls Royce. I am going to run an external fuel pump due to the OEM pump having a screw flange that would need to be duplicated in Aluminum. What size fuel feed and return lines are needed?

Well... fancy meeting you here!

You will need 3/8 fuel line @ 58 PSI head pressure to mimic the OEM pump.

Dan,Yep I am finally back at it. Finally got the headers mocked up to my liking and sent them out to Stainless Headers Mfg., Inc. fabricates custom headers in stainless and mild steel

Classic instruments is dupicating the Original Rolls gage faces with their dash instruments.
Since its 28 degrees and snowing the shop is the only place to be.
Thanks for the help
