Making new fuel lines. What do I need?

[In The Ten Ring]

So I got the carb back from the shop. Although it took 5 days to clean, he only charged me for an hour's work. AND he was able to reuse the old float so I can take the new one back!

The man said it was "full of fine rust" and he wishes he had taken a picture! He also thinks I should pour gasoline down the hardline and see if any rust comes out and if any does, to go ahead an put in new fuel line.

He suggested making my own from copper/zinc coated line from Advanced Auto.

What would I need to do that?

*More background: the gas tank has been removed and "renewed," all fuel lines have been blown out by compressed air, and the flexible connection hoses have all been removed and will be replaced.
