I used a universal goodyear hose from Advance; had to order online, and it only came in 4 foot lengths, but I believe it was about 50 bucks or so. It was a pain in the arse getting to curve it around the frame, but it finally came together. I'm not sure if there are some brands/types that are more flexible, but the goodyear stuff is pretty tough.

Cheers,

JK
