327/350 Fuel Line Size?

I just purchased a new pump-to-carb fuel line for a 66 327/350. It is 5/16 OD tubing. Is that the correct size? Should it be 3/8" OD?

The main tank-to-pump line is always 3/8", but the pump-to-carb line on 327's is 5/16".

Thanks. For some reason I had it in my head that the 327/300 was 5/16 and the 327/350 was 3/8. I'm good to go then.

On some Chevy car lines of that era, two different sized lines were used, depending on the engine.
