Fuel Pump Autopsy
I cant say I found anything outwardly wrong with it and given the intermittent nature of the problem, I am not surprised. Nor would I ever profess to have ANY idea of what I was looking for other than something obvious.
More hours on the new pump with the same observation; the pressure is a steady 10psi above where it was before the swap without any wavering.
Here are pictures of the inside of the fuel pump.
