Our water pump housings are supplied by CAT. We have sold thousands upon thousands of them over the past 5 years. We've used them time and time again on our dyno test engines and our daily drivers with absolutely no problems.

These same exact housings have also been (and are currently being) sold by Hughes engines, Chenoweth speed and machine, and many other vendors on both ebay and Moparts. Obviously, they haven't been having any of these problems either.
