SOURCE: Fuel pressure regulator
Very easy if you have the new one just look at how it is mounted, most times just a couple of retainning screws and it comes right out, bleed the fuel system of pressure before you take it out or put a rag over it, there will be about 40 PSI in the fuel rail.

SOURCE: 1989, Cutlass Supreme, 3.1, what
30-40psi. one thing to check first is the vaccumm hose at the fuel pressure regulator, take it off, if it leaks fuel, replace the regulator. when the engine is running you should have approx 30psi, with vaccumm hose off, approx 40psi.
