American Hose will work, but they seem to be pricey when not ordering bulk. Try "Royal Brass and Hose" on Williams Drive in Marietta. The guys are generally good and can usually make something while you wait.

If you'll call the dealer back and get the O.E. number on the hose, I'll see what I can find. P.M. me.
