Im running an older carbed engine, now with a regulator does anyone have any sizes or places to look online for what ya'll did and how you did it? Just needing some ideas. Thanks guys!

 

3/8's Feed, 5/16's Return. I used existing fuel line from a donor car with the original saginaw fittings, flared the fuel lines, reused saginaw fittings, and shaped the lines myself in the direction I needed them to go, or you can go the braided fuel line route...
