Now there's good advice! Go to the auto parts store, ask the busy parts
counter guy to paw through every hose in the place, find one kinda-semi
like the one you have, take it home and try it. You may have to go back
a couple of times, but I'm sure the parts guy will love seeing you come
in. Then you may get one similar, may have to kink it around corners,
but, hey, there IS the possiblilty that it won't overheat! OR, you can
get the correct hose for the application.
