Sorry to be so late getting back to you. I was out of town. I read your post to sab about his heating problem, so I guess I understand how you ended up with a used pump on your hands. I think I want to go with a new one, but I'm curious about where you found your new one, and how much it cost? It sounds like a pretty easy job, so I think I can take care of this one on my own if I can find the part.
