An improved fuel rail for delivering fuel to a fuel injector for an
internal combustion engine is provided that reduces the weight of the
fuel injection system, greatly reduces manufacturing costs by eliminating
expensive manufacturing methods, such as brazing, high heat welding, post
plating, blow molding, and extrusion, and enhances low-cost, low-energy
methods for attachment of fuel system components to the fuel rail. The
improved fuel rail includes an tubular body defining a fluid chamber and
having an inlet through which fuel enters the fluid chamber and a fuel
injector port in fluid communication with the fluid chamber. The port is
configured to receive the fuel injector. The tubular body is formed as a
laminate having an inner metallic layer and an outer polymeric layer. The
inner metallic layer may comprise aluminum and the outer polymeric layer
may comprise nylon. Plastic or metal components can be attached to the
laminated tubular body while providing a fluid tight, pressurized joint.
