James,

I just replaced my fuel pressure regulator not to long ago using Dino's excellent write up:

This should give you all the information that you need. There is a little fuel pressure, but if you cover the regulator with a rag when you crack it loose you should be fine.

The one thing that I will caution you about is to hold on to the allen wrench when you take the bolt off of the back of the metal cover. Mine dropped down the back of the engine never to be seen again. I heard it rattle around as it fell, but it made a soft "whump" when it stopped and I just couldn't find it so I had to cut another one down.

Good luck.
