Saw that too. Full circumference quarter prolly caused the broken clip there. It was forced down while squeezed out from under the gasket.
Should look like this. Flat top against valve cover so it cannot escape.

Only one way to find out. Gather data and run it through this analysis:

What are your thoughts?
would a thinner but wider pocket on the pump gear cause more or less of a tendency for aeration?
I’m assuming the gear tooth itself has became a smaller width so the same volume can be pumped at each rpm.

I doubt work would want me to take our FFT equipment offsite for a test on a 21 year old Powerstroke.

If you have fewer lobes with deeper pockets, I'm assuming there will be greater suction within the pumping chamber vs more lobes with more shallow pockets. But I'm sure there's plenty of nuance that'd be needed for a proper understanding.
Definitely the latter haha the former is for Fridays and Saturdays
