Abstract
A fuel pressure regulator in either a returnless or fuel return fuel system for an automotive vehicle is integrally mounted between a fuel rail and an intake manifold port of the engine. A mounting cup is provided on the fuel rail and fuel entry or exit openings for the regulator are sealed by O-ring seals disposed between the regulator and the mounting cup on opposite sides of the fuel openings. The side of the regulator remote from the fuel chamber has a vacuum reference port received in a passage of an intake manifold boss and is sealed to the passage therein by an O-ring. By inserting the pressure regulator into the mounting cup with the O-ring seals and the vacuum reference port of the regulator into the passage of the intake manifold boss, the regulator is clamped between the fuel rail and engine manifold without ancillary connecting elements.
