An apparatus as defined in claim 10, further comprising a deflection shield coupled to the central hub portion to restrict the flow of liquid moving from a fuel tank toward the passageway. 14. An apparatus as defined in claim 13, wherein the deflection shield is coupled to the central hub via a fastener. 15. An apparatus as defined in claim 1, wherein a surface of the body has a convex contour shape to prevent liquid from entering through the passageway. 16. An apparatus as defined in claim 1, wherein the membrane layer is integrally formed with the opening of the body. 17. An apparatus as defined in claim 1, wherein the membrane layer allows continuous flow of gas or air therethrough. 18. An apparatus as defined in claim 1, wherein the passageway provides at least a 90 mm2 venting area. 19. An apparatus as defined in claim 1, wherein the perimeter of the opening defines a generally trapezoidal shape. 20. An apparatus as defined in claim 1, wherein the entire membrane layer is disposed within the opening. 21. A fuel cap apparatus, comprising: a body having a surface that defines a first side of the fuel cap and a second side of the fuel cap, the first side being opposite the second side, the first side at least partially defining a cavity, the body having a cylindrical portion extending from the body toward the cavity;a passageway formed by an opening in the surface of the body, the passageway defining a perimeter, the passageway and the perimeter being radially spaced relative to a longitudinal axis of the cavity, the passageway to fluidly couple the first side of the fuel cap and the second side of the fuel cap; anda membrane layer disposed inside the opening between an outlet of the opening and an inlet of the opening defining the passageway, the membrane layer to permit flow of gas through the passageway between the first side and the second side and substantially restrict flow of liquid through the passageway between the first side and the second side. 22. A vented fuel cap as defined in claim 21, wherein the membrane layer is integrally formed with the passageway. 23. A vented fuel cap as defined in claim 21, wherein the membrane layer is coated with a fluoropolymer material. 24. A vented fuel cap as defined in claim 21, wherein the membrane layer comprises a stainless steel mesh. 25. A vented fuel cap as defined in claim 21, wherein the first side comprises an interior side of the fuel cap and the second side comprises an exterior side of the fuel cap. 26. An apparatus as defined in claim 21, further comprising a deflection guard coupled to the cylindrical portion and having an annular flange, the deflection guard, the annular flange, and the body to form a tortuous path to substantially restrict the flow of liquid from the first side to the second side via the passageway. 27.
