The dealer might know the#. Sometimes you can find a like diameter hose for another application, and cut out the section that fits yours. Some auto part stores will have a big wall, or rack of them. Was me I might start at a Napa store. They might list it. (truth be told, I used a copper "L" below my bottle"). With a handle like "Flintatone", I get away with stuff like that. I'm sure you could find some ,(5/8?) with a bend you could cut to fit sweet. Just look at what they have. (Btw, 1/2 inch copper, with a fitting is about 5/8 OD.)
