Bumped one of my AC hoses the other day and heard a slight hissing sound. I wriggled it some more and lost my freon. I never actually saw the leak but could feel/smell it coming up from behind the radiator. I suspect I have a small failure in one of the metal lines that the AC hoses connect to. I'll probably get one from a boneyard down the street, but would rather give one of you guys the chance to get rid of an old one if you have it first.
