I noticed that at idle with the replacement pump, the fuel pressure was extremely stable and was about 6-6.5 PSI. The old pump would indicate pressure from 2-5.5 psi at idle with the needle moving rapidly.
After a few minutes of the engine idling in the driveway and no leaks encountered, I went for a drive. I drove about 10 miles in stop and go traffice and on a couple long of back roads. I didnt have any sudden shutdown issues at this time.
I also noticed at speed that the engine was no longer missing/stumbling randomly.

This video is at idle, new mechanical fuel pump
This is a visual check of the primaries at idle, to check for bleed over. There was not any, so its looking good that the mechanical fuel pump pressure is goooood.
