Abstract: A fuel rail assembly with crossover conduits for communicating fuel between two fuel rails of a fuel-injected, spark ignited internal combustion engine is provided. The hose has a body with a mechanism for damping pressure pulsations within the fuel rail assembly.

Abstract: A fuel delivery system is provided having a fuel rail with an outlet. A fuel injector is provided having a body with an outlet and a generally tubular inlet. The tubular inlet of the fuel injector is generally axially slideable into the fuel rail outlet. The fuel injector outlet has a generally noncircular cross-sectional shape and is torsionally restrained by the fuel rail outlet.

Abstract: A multiple pump fuel delivery system is provided, which in one preferred embodiment includes a tank. Mounted within the tank are multiple fuel pumps. The fuel pumps have intakes connected to filters. One pump may be connected to a fuel only passing filter, and another pump may be connected with a fuel-water mixture passing filter. Fuel from the outlets of the pumps is delivered past non-return check valves through a manifold. The manifold is connected with a pressure regulator valve, which is fluidly communicative with the engine of the vehicle. A relief outlet is also provided to return excess fuel.

Abstract: A polymeric tank assembly is provided having a polymeric container with a neck opening. A ring with protruding barbs is inserted within the neck opening and the neck opening is placed in compression by a surround collar. The ring can be connected with clamping arms which can be engaged by a clamping ring which retains an instrument within the tank assembly.

Abstract: A fuel delivery system arrangement is provided for the internal combustion engine. The arrangement includes a fuel rail with an outlet and a fuel injector for metering flow of fuel from the fuel rail into the internal combustion engine. The fuel injector has a body with an inlet, which inlet has an opening. A first sealing member is provided for engaging the fuel rail outlet and sealing the fuel injector inlet opening from a portion of the fuel injector body. A second sealing member is provided which engages the fuel rail outlet and seals the injector body providing a sealed control volume between the first sealing member and the second sealing member adjacent to the fuel injector body. A vent is provided connecting a sealed control volume with an area external to the fuel injector rail and the fuel injector body.

Abstract: An air fuel delivery system arrangement for an engine is provided, including an air manifold body, having a first set of runners for a first cylinder bank with inlets on a first side and outlets on a second side of the manifold body and a second set of runners for a second cylinder bank with inlets on a second side and outlets on a first side. And a first fuel rail is included, having outlets for connection with fuel injectors for delivering fuel to the first cylinder bank being positioned generally between the inlets of the manifold body. A second fuel rail is also included, having outlets for connection with fuel injectors for delivering fuel to the second cylinder bank being positioned generally between the inlets of the manifold body being generally vertically aligned with the first fuel rail.

Abstract: A fuel rail is provided for delivering fuel to a plurality of fuel injectors for a reciprocating piston internal combustion engine which in a preferred embodiment includes a sealed housing having an inlet for receiving fuel, the housing having at least first and second outlets for delivering fuel to fuel injectors, a first chamber forming a first control volume with an inlet connected with an interior of the sealed housing, the first chamber forming a vapor space for the sealed housing interior, and a second chamber forming a second control volume with an inlet to the first control volume, the second chamber forming a vapor space for the first control volume.

Abstract: A fuel rail is provided which includes a housing formed by a first member with a first thickness. A bracket is provided, connected to the first member to connect the fuel rail to an internal combustion engine. A second stamped member is provided and is sealably connected to the first member to form a control volume therewith. The second member has a second thickness that is materially lower than the first thickness. Accordingly, the second member has a wall to damp pulsations caused by the opening and closing of the injectors fluidly connected with the rail.
