The center stack is positioned within the cavity of the filter housing and attached to the housing, the center stack having an axial aperture in the top portion, the axial aperture having a circumferential surface, and a fuel filter. The fuel filter includes a filter base, an end cap having a top surface and a bottom surface opposite the top surface, an axial extension that extends from the bottom surface, and at least one prong attached to the axial extension, the at least one prong having an axial surface facing away from the top surface that axially locates the fuel filter in the housing against the circumferential surface, a filter element attached to the bottom surface of the end cap, and a pin attached to a filter base.
