The fuel psi regulator is located under the Intake plenum, and is relatively hard to change.

It is more time consuming than hard to change. I suggest you get your digital camera and take a pic of the top of the engine, before you start. This way you will be able to see where things go back later. Basically it is a process of taking a number of things off the upper manifold and then removing the upper manifold also called the plenum. I also like to use a piece of tape on both sides of all elec connections and begin numbering them 1 - 1, 2 -2 ....... I it is the first time and you work like most do it yourselfers, plan on one night to tear it down and the next to put it back together.
