Are you talking about the clear hose with the support webbing inside. That is commonly used for Soda/Fountain drink machines. But racers use it for their air to water intercooler. If so, Lowe's carries it in a variety of sizes.
As stated above try a hydrolic supply place. Here in KC we have Tompkins. It's the creal with the wire support. All that other stuff will collapse. Performance Hose Dist. has a really good deal on Starlite hose right now for a second option.
