Where is fuel pressure regulator located on 1997 Chrysler cirrus 2.5?

On a 1997 Chrysler Cirrus 2.5L, the fuel pressure regulator is integrated into the fuel rail. It's not a separate component like on some other vehicles. You'll find it on the fuel rail itself, usually towards one end. You'll need to look closely at the fuel rail; the regulator is usually a small, somewhat inconspicuous part of the assembly.
