The solenoid actuated fuel injector includes a valve group including a valve body having an upstream end, a downstream end and a longitudinal axis extending therethrough. The valve group also includes an inlet tube having an upstream end, a downstream end, and an inlet tube channel, the downstream end of the inlet tube is connected to the upstream end of the valve body. The inlet tube includes at least one formed slot. The valve group farther includes an armature/ball assembly reciprocally disposed in the valve body along the longitudinal axis. In addition, the downstream end of the inlet tube is spaced a predetermined distance from the upstream end of the armature/ball assembly. The solenoid actuated fuel injector further includes a power group including a coil assembly that cinctures the inlet tube, a housing that encases the coil assembly, and an overmold that encapsulates the housing and coil assembly. The overmold includes at least one overmold slot that is formed in the overmold. The power group also includes a retainer that extends through the at least one overmold slot and the at least one inlet tube slot, the retainer retains the power group to the valve group. A method of manufacturing the injector assembly and a method of operating the injector assembly is also provided.
