Steve----when I order tubing the prices come down as the number of feet go up so I'm always adding stainless for brake and fuel lines and lengths of tubing that have a od/wall thickness combo to result in a standard tap size id for threading---I think 1/2 .083 results in tap size for 3/8??????????????anyway, don't know what the availability and sizes available over there but there are 2 or 3 big suppliers right near here and they are always ready to talk to racers!!!!!!!!!!
