I ordered a P4070 Carter pump and a 12-804 Holly pressure regulator from StreetsideAuto.com- 104.00 bucks and some change.

There is a nut on the reg to adjust the pressure. I may add a mini-guage like Brad has to dial in the correct pressure.

The thing is going to run better than new by the time I'm done.
