I pointed out the fact that the 94-97 OEM fuel system is a REGULATED RETURN, and that the 99-03 OEM fuel system is a REGULATED SUPPLY. I make this distinction based entirely on the placement of the fuel pressure regulator in the system, and whether it is regulating the pressure BEFORE the fuel rails/injectors, or AFTER.
