<p>A fuel rail damper (60) for use within the fuel rail (10) of an internal combustion engine includes a flexible tubular diaphragm (70) which extends along the center of the fuel rail. The distal end (80) of the tubular diaphragm is closed and the proximal end (90) of the tubular diaphragm is open and connected to a diagnostic fitting (100) at one end of the fuel rail. This fitting includes a diagnostic valve core and a cap (120) which permit external servicing. The diagnostic fitting is removable which permits the fitting to be easily installed or removed, thus facilitating replacement of the fitting, if necessary. The diagnostic fitting is sealed after the tubular diaphragm is pressurized to a pressure below the operating pressure within the fuel rail.</p> |
