On the early cars, it was a vacuum operated diaphragm device on the fuel rail, as in the diagram.
The early fuel system included a return fuel line and had a fuel rail mounted fuel pressure regulator. For 2002, there is no return fuel line and the fuel pressure regulator is mounted in the fuel tank.
