I had the very same problem as my sb was sitting very low and I couldn't find a hose that would work w/o kinking. I found a length of vacuum hose that was used in the car wash business at the vacuum stations and was rated at 250 degrees and was flexable enough to use w/0 kinking. So far after 6 years no problems. Try you local car washes and see if they have any of this hose. I think it was made for high temperature applications but can't rember the name.
