Fuel filter

A fuel filter, comprising:

• a filter center support having a first portion extending along a first axial length, and a second portion extending along a second axial length, the first portion having a first inner diameter that is greater than a second inner diameter of the second portion, and having a first inner contact surface at the first inner diameter;
• and
• a filter base having an opening, the opening having an opening diameter and a second inner contact surface;
• an end cap having a prong, the prong having an axial surface facing away from a top of the fuel filter, and the axial surface axially engages the fuel filter within a filter housing against a flat circumferential surface of the center stack to axially position the fuel filter, the end cap having an undersurface;
• a filter element attached to the undersurface of the end cap;
• a water separator at the filter base of the fuel filter and configured to engage with the filter housing;
• and
• a pin attached to the water separator;
• wherein the fuel filter is positioned within the filter housing at a first axial location and at the first inner contact surface and contacts with an outer dimension of a radial extension of a center stack at the first axial location when the fuel filter is positioned within the filter housing, and contacts the center stack at a second axial location at the filter base.
