Here's what I've run on my hemi for many years w/ no issues at all. Milodon pump w/ a stock cast iron pump cover. 7200+ rpm. Who popped a wheelie and bashed his oil pan on the return to earth  I'm glad it didn't tear it open   Yep, I've done in it a few times now. The last time it did tear the pan open. Put a nice Charlie's pan on it now, but the car may be retired for a while.

I had a titan pump on my aluminum block, never had this problem being discussed. I went to dry sump due to lack of ground clearance. Titan drawback is very expensive! You are correct, I will probably step up to a Petersen multi stage dry sump system on my new race car for the local northwest no prep deal next year

Use one of the Peterson primer remote filter mounts. Spin it with a cordless till you have pressure and go. I would check both fitting hose joints on the suction side. If you're loosing prime you have an air leak period. Very cool! Didn’t know those existed. I googled them….SPENDY,!!!

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

Well I think I’m moving into the no check valve camp. Just wanted to post for anyone else thinking of installing a check valve.
Started the car Saturday to head out to test and tune and was letting it warm up when the oil pressure light went off -20lbs. Giving it a tad of throttle and the gauge would fall back just a bit. Shut the car off and prepped the lift, got back in and when I started it. it took 4-5 seconds to build pressure and the oil pressure was back up to 60. Drained the oil, pulled the check valve and the plunger was gone. Pulled the pump and filter looking for the plunger but didn’t find anything. I cut the filter open, clean as a pin. Not sure where the plunger is, but it will likely go back together without a check valve.
I had it out the week before and it was holding 40 lbs at idle once the oil was hot (VR-1 20/50 Dino) and it held 80lbs down track at 7200, so no issues. Just really thankful it came apart idling in the shop and not at 7200.

He'll probably cause a high rpm starvation problem, with all this bs and blow it up. Ain't no way I'm putting anything between my pump and its oil. I repeat.

If I had a dry start issue that worried me enough to try and solve it……..I’d install an accusump.
But, nothing I’ve built to this point has needed one.
