What size is the fuel line between the fuel pump and the Rochester BV 1bbl carburetor on a 6 cylinder 194 ci 1964 Nova with standard transmission?

Is it 5/16 or 3/8?

Slide a 5/16" open end wrench over it, probably 5/16".

I have the original 5/16" fuel line on my now 383 solid roller 72 Nova with no issues.
