Default Fluctuating fuel pressure

I finally bought a fuel pressure gauge, I hooked it up like the directions said, turned the key, no pressure. Started the car, the pressure jumped up to 37lbs give it a little gas the pressure goes up to about 42lbs and gradually drops the more gas you give it. Sometimes when I turn the key, it jumps right up to 40lbs or so, most of the time not. What do you guys think? Thanks alot guys.

How old are your fuel pump and fuel pressure regulator?
