I knew the 22100 and the 22135 pumps were the thin casting, but here's more.I found this through searching all of the links that I could find about oil pumps.

Ok, here is the deal on our pumps.
We have two cast pumps that use the M-Select heavy-duty castings. They are p/n 22138, and 22139. They are both meant for 8 1/4 inch deep pans. ALL our other cast pumps use Melling’s fairly new "lightened" casting.
We have been selling the "lightened" casting for approximately 8-9 months. We fortunately have not had any failures that we have been made aware of.
We are working with Melling now to come out with a Moroso branded pump that will replace all our "lightened" housing pumps with a better, stronger casting. That is in the works, but will not be done for a few months.
I am very sorry for the confusion. Doug got some bad info at first, and in the effort of trying to put everyone at ease, posted it before we caught the mistake. We are doing our best to get it all straightened out.
For street and MILD performance, I would have no worries running any of our pumps. For racing and hard-core apps, I would use our 22138 or 22139 pumps, or any of our billet pumps.
Thanks
Rick
