The fuel injector includes a power group subassembly and a valve group subassembly having a respectively connected first and second connector portions. The power group subassembly includes an electromagnetic coil, a housing, at least one terminal, and at least one overmold formed over the coil and housing. The valve group subassembly insertable within the overmold includes a tube assembly having an inlet tube and a filter assembly. A pole piece couples the inlet tube to one end of a non-magnetic shell having a valve body coupled to the opposite end. An axially displaceable armature assembly confronts the pole piece and is adjustably biased by a member and adjusting tube toward engagement with a seat assembly. A lift setting device sets the axial displacement of the armature assembly. The seat assembly includes a flow portion and a securement portion having respective first and second axial lengths at least equal to one another.
