80stech,
Thanks for the reply. I assume the difference is hose length. I put one on order to get it here on time. I think I ordered the longer one. I can trim it to the fit heater valve. A new valve is available for installation. The hose is so soft, I doubt it would last a harsh summer or brutal winter.

Does water flow through it when not in use? If not, it would be better to flow water to keep it cooler.
