I bet 5/8 would be plenty adequate. I did not even think about that being a source till I was already down the water line route. Either is way cheaper than the specific line sold for the purpose that I found, and plenty adequate. The other issue for me was as you mentioned, the shipping cost. It can get really high on bulky stuff. Thus the main reason for finding a local source for the bulky air line.
