Where is the Fuel pressure regulator on a 1993 Ford Aerostar AWD 4.0L?

On a 1993 Ford Aerostar AWD with the 4.0L engine, the fuel pressure regulator is integrated into the fuel rail. It's not a separate component like on some older vehicles. You won't find a standalone fuel pressure regulator; it's part of the assembly that sits on top of the fuel injectors.
