Default Brake Line Size.....

Would anyone know the size of the steel brake line on my 81? There is a rubber hose between the steel line and carburator and I want to replace the rubber with SS braided line.
I know, I could go outside and measure it, but the 81 is put away for winter storage. I would like to have the new line here when I take the car out of storage. TIA

Brake lines are 1/4 and main fuel line are 3/8

I am unsure of the return fuel line

If you're referring to the line to the vacuum booster, it's 3/8".
