Where is the fuel pressure regulator?

Where is it located on the ls1? Is it the piece between the fuel rails? I think mines faulty..would a adjustable one be the way to go?

At the back of the intake manifold mounted on the fuel rail, getting an adjustable one wont do anything unless u have crazy mods.

Ah no, the piece on your fuel rail is a fuel pulse dampner. It just dampens the pressure fluctations from injector operation. The regulator on your car is located in the tank.

They don't make an adjustable FP regulator for our cars (99-up) unless you have seriously altered your fuel system. Sorry...
