Carl came up with a nice and simple solution, making me feel silly for
not thinking of it myself. Turns out the highest temperature flexible
hose I can find is brake hose, which is rated to the dry boiling point
of DOT 4 brake fluid, around 450 F. This is even higher than turbo or
stainless steel hoses, which are rated to 300-350 F.
Thanks for the help!
