Just installed the Hardin SS pump for this season. Have seen the long life and run dry impellers and the reviews show that they do work great for Alpha's, but not so much on the Bravo's, at least so far as the reviews.
Interesting about the Hardin pump, I noticed there is a slight dimple inside the bore of the housing. This same dimple is not in the composite housing. I wish now, I would have waited on the install because I replaced the oil cooler and pump for this season. Replacing both does not give me a baseline of the old pump compared to the new. I really want to change the pump back to the old, but not so much to actually do as yet
