Gaunt Hose Size

Anyone can tell me what the size of hose (diameter) so I can pick up some at the Home Despot? Thanks!

I'm not 100% sure on the diameter, but if you get one of the spray heads for a kitchen sink with the hose attached, its pretty much what you want...has the correct webbing inside the hose. Kinda sux though, cause you have to buy the whole head attachement with it and you end up just cutting off the hose. I think they run around $9. There may be somehting better out there, but this is the best looking hose accuracy wise that I've come across. I think I got mine at menards, but guessing HD will have the same thing.

8mm (roughly 5/16") ID X 14mm OD
