Abstract
A fuel system has a fuel injector directly mounted with a fuel rail. The fuel rail has a body with interior and exterior surfaces. The interior surface defines a volume. The exterior surface surrounds the interior surface. An aperture extends between the interior and exterior surfaces in fluid communication with the volume. The fuel injector has an inlet tube with an inside surface that defines a flow path through a portion of the fuel injector, and an outside surface that surrounds the inside surface. The fuel injector is disposed so that the flow path is in fluid communication with the volume. A rigid connection is disposed between at least one of the interior and exterior surfaces of the fuel rail and the outside surface of the inlet tube, the rigid connection securing and hermetically sealing the fuel rail with the fuel injector.
