'70 Dart 392 Project; what direction?

Waiting for a few parts to arrive tomorrow and tuesday and should have the Dana 60 built this week. Also planning on running brake and fuel lines. Got an EFI tank ordered with 255lph tank/sending unit as well. Painless wiring is ordered as well.... Last big purchase after this will be megasquirt system I think and then exhaust. Everything else should be minor.

Can't find any info with the google at the moment, but does anyone know what size fuel line I should be running? I'm guessing 5/16-3/8" based on OEM stuff but wanted to ask if anyone knows off the top of their head. EFI tank comes with rubber fuel lines but I'd rather run hard lines up to the engine bay. Thanks

Mike
