ABSTRACT:
An integral pressure damper is designed for use with an internal combustion engine having a fuel return line and a fuel rail in a fuel system that requires a damper. The integral pressure damper comprises a fitting securable to the fuel return line, and a damper assembly securable to the fitting. The fitting is securable to the return line. The present invention allows the flexibility of attaching the return line to the fuel rail using braze or any other suitable attachment process, before the damper is attached to the return line. The damper is subsequently secured to the fitting, such as by crimping a housing of the damper to the outside of the fitting, or by crimping the fitting to the outside of the housing.
