Abstract: Various methods and systems are provided for a leakage passageway for a fuel injector of a common rail fuel system. In one embodiment, a fuel injector for an engine comprises an injector accumulator, an injector flow limiter valve configured to control a flow of fuel from a common fuel rail and into the injector accumulator, and a leakage passageway coupled between the injector accumulator and an inlet of the injector flow limiter valve, the leakage passageway bypassing the injector flow limiter valve.
