I'd run the biggest fuel line I could, you can always reduce it down.
You can also run a fuel regulator if you need too.
If you run it to small you'll have to go back and run all new line though.
Thats just what I would do. Kurt

3/8 is the normal size. That is plenty unless you put in alot larger engine..like a BBC.
A stock fuel pump for the application will keep up with the engine. Just dont buy Chinese crap ;)

a mild 400 with a 600CFM carb will be FINE with a stock pump and a 3/8" ( stock ) line.
