ABSTRACT:
A low profile fuel injection rail assembly for supplying fuel to a plurality of electromagnetic fuel injectors on an internal combustion engine. The fuel rail assembly is characterized by a plurality of fuel sump chambers defined by linearly spaced apart nodular rail sections which are connected in series by a plurality of tubular rail sections having cross sectional openings of reduced size. Each sump chamber surrounds an injector socket recessed into the bottom of the rail or an injector receptacle recessed into the top of the rail. Fuel is supplied to the injectors through inlets in the sockets or receptacles. Fuel supply and return fitments are mounted at one end of the rail along with means for connecting a fuel pressure regulator having two coaxial fuel passageways.
