Just trying to figure out how to remove the fuel pressure regulator without removing the fuel rails. Just curious how it may be done, if possible.

Removing Fuel Pressure Regulator without removing fuel Rails, Possible?

Yes... I've done it several times. You need to release the fuel pressure as Kevin described. Release the metal clamp that holds the hard lines in the bracket at the rear of the intake - Torx screw with the head facing down . Remove the spring clip that holds the hard line in the FPR. Twist as you pull, and make sure the o-ring is still on the hard line when it comes out of the FPR. Remove the single T-27 screw that holds the FPR to the back of the intake. Rotate and pull back, making sure the o-ring is intact.
Reverse procedure to install.

I got it. Thanks guys. I just couldn't see what was happening back there. Very easy actually. You guys may remember i was trying to figure out why it seemed like I was gettin too much fuel. Well, I had the SLP FPR anyway so i decided to put it on. Just got back from a drive with it set at 34 psi idle. Lower than should be, but I did a plug check and they look about perfect. the car seems to be running stronger as well. I dunno why cuz I thought the PCM would keep the fuel pressure in check. Thanks a million tho guys.Life is not a journey to the grave with the intention of arriving in a well preserved body, but rather to skid in broadside thoroughly used up and totally worn out, loudly proclaiming......WOW WHAT A RIDE!!!

The PCM can't control the fuel pressure. All it can do is adjust the long term fuel corrections, to alter the injector pulse widths, and compensate for the reduced fuel pressure. "Gains" from lowering the fuel pressure are real, but they are temporary.Fred
