You likely don't NEED a regulator as it will never pull enough to hurt anything. Just my .02

I first mounted mine in the Indy valley tray. It filled my catch can on the first dyno pull even with a Morose 22635 positive seal vented fitting. I moved it to the valve cover and after 17 pulls it barely had anything in the catch can.

You likely don't NEED a regulator as it will never pull enough to hurt anything. Just my .02 I heard that anything over 12in/Hg was too much on a wet sump. I had to adjust mine to get under that using a 4 vane Moroso BTW. I've seen folk mount the reg on the opposite rocker cover to the take off, this way there is an air flow through the engine and you will pull oil through.

This is exactly what GZ says to NOT DO, don't suck outside dirty air across the motor  I've heard and know racers that shoot for 17.0 inches at the starting line with a regular wet sump oil system  I get barely 5.0 inches with my current GZ pump in neutral revved up  The next motor will have the Moroso 4 vane pump on it and I'll do every thing I can to seal it up so it holds a vacuum

I started off w/ an Aerospace vacuum pump kit which is a total piece of crap. Had 2 pumps fail and the mandrel is junk too. Never pulled more than about 6-7" w/ the regulator closed.
The regulator is mounted on the intake side of the pump itself.
I switched to a Moroso 4 vane pump and CV products mandrel drive setup and couldn't be happier. It pulls 10" at half throttle where it is set right now...honestly not sure what it pulls at WOT.
Mine pulls from the driver's side valve cover w/ no baffle at all. No issue pulling too much oil. I drain it after I get home from the track.

Do you have a gauge on the car so you can see how much vacuum it's pulling?
Put the line on the valve cover first. You may not need a regulator at all depending on how much it pulls.

I have the same reg as pictured on my Hemi also. I only picked up about 8 hp with the pump and mine also make 10in of vac. But that was mainly due to that I run an old school std tension 1/16, 1/16, 3/16 ring pack due to being a street car. Others results will vary from engine to engine.

If hood clearance is an issue you can put it on the inside portion of the valve cover between rocker arms possibly. Not sure what head and rocker set up you have but its worth looking at. Along with the Moroso baffle you should be way better. UNLESS you have an external leak.  nice information

The engine in the Cuda went 404 passes at its last freshen up. It pulls 16-17" of vacuum and there has NEWVER been an issue with the pins period. That was freshen up number 2 on those pins and pistons, they had a total of 782 laps on them since new when I sold it. Still at 16-17" of vacuum, never an issue
In the heads up car we pull 20-21" each pass. Engine comes out every year. Never an issue with pins or pistons. Both ran 4 vane enhanced Moroso pumps and both are wet sumps. Just stating my EXPERIENCE not speculation.
