I used a new Actron fuel pressure gauge. It's fairly inexpensive, but seemed to perform well. Since the pressure read in spec at the upper limit, it seems like the gauge is reasonably accurate.

With some contortions, it looks like the regulator can be replaced without removing the plenum. Can anyone confirm this?
