Well I haven't got into it yet as I just limped her home the last 10 or so miles, but it looks like the Meziere pulley seized up and took the belt out. Luckily I have a stock pump as well as another electric sitting in the garage somewhere. I have always been a big proponent of using a Meziere pump and I don't think this is going to sway me any different. This is my first failure in over 20 years of using their products.
