Abstract: A fuel rail assembly has a pair of fuel rail bodies each of which has a bore extending parallel to the fuel supply passage. Each bore has a plug dividing the bore into inlet and discharge regions. The inlet regions are interconnected by an inlet crossover tube, and each inlet region opens to its associated supply passage through a window and a restriction at one end of the associated fuel rail body to balance fuel flow to the supply passages. At the other end of each fuel rail body, a cross bore extends through the discharge region to the supply passage, and discharge tubes received in the cross bores discharge fuel from the supply passages to a pressure regulator.

Abstract: A fuel supply member surrounds the perimeter of a pressure regulator diaphragm and sealingly engages the pressure regulator base and the pressure regulator cover to completely enclose the perimeter of the diaphragm in the fuel supply system.
