some good heavy duty high temp rubber hose and 2 screw clamps will get you by... I know someone that has had that setup on their td for years with no issues. I think you have to cut above and below the flex fitting (remove the flex fitting) and then slide the hose on. Finding a used one by itself might be a chore.
