I want to put conduit in the wings and called Vans to place an order, however when I asked the parts department what size tube to order, I was told that I need to talk to a tech guy between 0700-0900 or 1530-1630 to get my answer. So I was hoping that someone here can tell me what size of tubing I need to order and how many feet? Would it be better to order it locally some where?
