Pulsing doesn't sound good to me. That might be the pressure regulator popping open/closed which can suddenly stick.

The gauge set I ordered came in (gotta love real parts stores that can get stuff the next day) and after at least 30 minutes of running, I had 25 PSI at idle. I did notice pulsing with it (got better as it got hotter, was about a 5 PSI pulse at its worst and about 1 PSI when I shut it off) but I think that has more to do with it being a gear type pump than anything else. Once it quits raining, I want to drive it around a little bit to get the oil good and hot to make sure. Speaking of the gauge set, it has 2 gauges with it. One goes up to 50 PSI, the other goes up to 600 PSI. If I need to do any pressure tests with an automatic transmission, I'll have the gauge to do it. If not, I'll have a neat looking gauge set.
