Oh and lets see, you by a used car and all of us suddenly the manufacturer discovers a flaw in that specific model. All you have to do is bring it back to ANY of thier dealerships and they will replace the part FREE of charge.
see here
Government-Initiated Recalls and more importantly After-Warranty Assistance Programs
really its up to swiftech, they know that its a defect with the pump, they know that its not the users fault (dont BS me here about abusive use, its a known problem), Its up to them to decide whether to Honor the RMA or not. If they decide not to and do this to one too many people, word will start going around, and you cant stop that. You should know that better then anyone Bill. I know that you dont have to replace it as per your stated warranty, and that the user might have lied to you, but it doesnt change that you
initially sold a defective product.
