An injector including a self-actuating three-way valve lodged in a passage between the fuel injector supply inlet and a control valve. The three-way valve permits fuel to flow from supply through to the control valve during a metering mode of operation while prohibiting fuel to be dumped to the supply line during the pre-injection timing phase of operation.
