摘要： A fuel injector with a neck at an upstream end and a downstream end located at a distal end from the upstream end, a fuel channel extending from the upstream end to the downstream end and defining a substantially longitudinal axis, and a check valve located in the fuel channel proximate the upstream end; and a fuel rail with a housing defining an opening having a substantially longitudinal axis passing therethrough, and a one-way flow inhibitor is located in the opening. When removing the fuel injector from the fuel rail, reducing leaks by biasing a plunger of the check valve against a seat of the check valve in the fuel injector and biasing a plunger of the one-way flow inhibitor against a seat of the one-way flow inhibitor in the fuel rail.
