The fuel pressure regulator is located on the driver side of the 3100 engine with one star drive screw at the end of the front fuel rail, just above your coolant temperature sensor. It has a pretty large nut with a steel fuel line coming out of the bottom of it.
At the top is about a 1/8" fitting that a capillary sized vacuum line attaches to it with a 90 degree elbow. That vacuum line goes back and connects underneath to the MAP (manifold pressure sensor).
The MAP is a little rectangular block with one vacuum hose connection underneath and one electrical connector with 3 pins. The MAP sensor is at the top rear of the engine right in front of your coil pack.
Hope this helps you locate the fuel pressure regulator.
Most of the engines I've seen in Buick, Pontiac, Chevy and Oldsmobile are almost identical in set up under the hood.
