What is the stock fuel pressure run at? My gauge is reading/ bouncing around 3.75-4.25 psi.

My FSM indicates normal pressure to be 3.5 - 5 psi. Sounds like yours is right where it needs to be. If your guage is teed directly into the output of the stock pump it will bounce because the output of the pump is not steady; it pulses as the arm is pushed up and down by the cam.

Growing older is unavoidable but growing up is strictly optional.

I thought it should be more like 6 psi but, if thats what the FSM says, then that good enough for me.
Thank you.
