An evaporative venting system for use in an internal combustion engine and a method for venting fuel vapors are disclosed. The evaporative venting system includes a containment chamber at least in indirect communication with a fuel tank and a passageway defined within the containment chamber and having an inlet opening and an outlet opening. The inlet opening is at least indirectly in communication with the fuel tank and the outlet opening is at least indirectly in communication with an evaporative chamber such that the passageway provides a vent path between the fuel tank and the evaporative chamber such that the vent path allows for both the venting of fuel vapors from the fuel tank and the intake of air into the fuel tank during all angles of positioning of the fuel tank.

1. An evaporative venting system for use in an internal combustion engine, the system comprising: a containment chamber in at least indirect communication with a fuel tank; anda passageway disposed substantially within the containment chamber and having an inlet opening and an outlet opening; anda redirecting portion that at least partially changes the directional path of at least one of a fuel, fuel vapors and air;wherein the inlet opening is in at least indirect communication with the fuel tank and the outlet opening is in at least indirect communication with an evaporative chamber such that the passageway provides a vent path between the fuel tank and the evaporative chamber;wherein the passageway further includes a first passageway portion that extends at a descending angle from the outlet opening to the redirecting portion;wherein the passageway further includes a second passageway portion that extends at a descending angle from the redirecting portion to the inlet opening; andwherein the vent path permits both the venting of fuel vapors from the fuel tank and the intake of air into the fuel tank during all angles of operation of the engine. 2. The evaporative venting system of claim 1, wherein the evaporative chamber comprises an atmospheric vent to at least one of receive intake air from the outside and emit fuel vapors to the outside. 3. The evaporative venting system of claim 2, wherein the evaporative chamber further comprises an evaporative filter for at least one of filtering and purging the fuel vapors. 4. The evaporative venting system of claim 1, wherein the passageway is at least partially formed integrally with the fuel tank and is substantially enclosed by the containment chamber. 5. The evaporative venting system of claim 4, wherein the redirecting portion is substantially semi-circular in shape. 6. The evaporative venting system of claim 1, further comprising a base portion including a base plate, and the passageway further comprises a circular tube having an inlet portion, the redirecting portion, and an outlet portion, the inlet portion being situated above the base plate and the redirecting portion being substantially situated above the base plate and extending through the base plate to the outlet portion. 7. The evaporative venting system of claim 1, further comprising a base portion at least one of secured to and partially formed integral with the fuel tank, the base portion at least partially defining the containment and the evaporative chambers. 8. The evaporative venting system of claim 6, wherein the inlet portion extends from the inlet opening to the redirection portion and the redirection portion at least partially alters the angle of the passageway in an upward direction towards the outlet portion. 9. The evaporative venting system of claim 8, wherein the outlet portion extends through a fuel tank top surface and is connected to the evaporative chamber via a passage. 10. The evaporative venting system of claim 1, wherein the containment and the evaporative chambers are separated at least partially by a chamber barrier to at least partially limit the flow of fuel from the containment chamber into the evaporative chamber, the chamber barrier having a barrier opening to allow the flow of air or fuel vapors between the containment chamber and evaporative chamber. 11. The evaporative venting system of claim 1, wherein the first and the second passageway portions are connected together by the redirecting portion to form a substantially U-shaped configuration to change the direction of the flow of air, fuel vapors or fuel through the passageway. 12. The evaporative venting system of claim 11, wherein a passageway barrier is situated substantially between the first and the second passageway portions to prevent fuel from moving directly between the first and the second passageway portions absent the redirecting portion. 13. The evaporative venting system of claim 1, further comprising an inlet opening comprising an orifice which provides direct contact with the fuel tank. 14. The evaporative venting system of claim 13, wherein the inlet opening is formed as a pit for facilitating fuel collection. 15. The evaporative venting system of claim 1, wherein the passageway is at least partially integrally formed within a base top portion of a base portion defining a channel that is at least partially depressed into the fuel tank. 16. The evaporative venting system of claim 1, wherein an edge barrier substantially encloses the perimeter of a base top portion of a base portion to at least partially define the containment and the evaporative chambers. 17. The evaporative venting system of claim 1, wherein the passageway is formed of raised walls on a base top portion of a base portion within the containment chamber and situated above the fuel tank. 18. A method of venting fuel vapors from a fuel tank, the method comprising: providing (i) a base portion in operable association with a fuel tank; (ii) a containment chamber defined at least in part by the base portion; and (iii) a passageway disposed substantially within the containment chamber and having an inlet opening and an outlet opening, wherein the inlet opening is at least indirectly in communication with the fuel tank and the outlet opening is at least indirectly in communication with an evaporative chamber; andventing fuel vapors from the fuel tank into the atmosphere through the evaporative chamber via the passageway, when the fuel tank is positively pressured, wherein venting fuel vapors from the fuel tank further comprises: guiding the fuel vapors along an ascending second passageway portion within the passageway;redirecting the fuel vapors in at least a partially opposing direction from the second passageway portion through an ascending first passageway portion of the passageway; andguiding the fuel vapors from the first passageway portion into an evaporative chamber via the outlet opening. 19. The method of claim 18, wherein the passageway defines a vent path for both the venting of fuel vapors and the intake of air during all angles of operation. 20. The method of claim 18, wherein the venting of fuel vapors further comprises: filtering the fuel vapors through the evaporative chamber using a filter media; andexiting the fuel vapors from the evaporative chamber through an atmospheric vent. 21. The evaporative venting system of claim 1 in combination with an engine. 22. The evaporative venting system of claim 1, wherein at least a portion of the passageway has a substantially circular path.
