Where is fuel pressure regulator on 2003 Chrysler town and country?

On a 2003 Chrysler Town & Country, the fuel pressure regulator is integrated into the fuel rail. This means it's not a separate component you'll find easily accessible; it's part of the assembly that distributes fuel to the injectors. You'll find the fuel rail on the top of the engine, near the intake manifold. To access it, you'll likely need to remove some parts of the intake system.
