Fuel fill apparatus for use with fuel tanks are described. An example fuel fill apparatus includes a body to removably couple to a neck of a fuel tank. The body has an opening to receive a fuel nozzle and guide liquid fuel from the fuel nozzle to a cavity of the fuel tank. A nozzle retainer retains the fuel nozzle in the opening. A positioner in the opening offsets the fuel nozzle relative to a central axis of the opening such that an aspirator of the fuel nozzle is positioned adjacent an inner wall of the opening when the fuel nozzle is inserted in the opening. The positioner maintains a fuel nozzle outlet opening substantially parallel relative to a central axis of the opening during a fueling event.

1. A fuel fill apparatus comprising: a body defining a fuel fill passageway having a first opening to define a throat area, a second opening to receive an end of a fuel nozzle, and a third opening to guide liquid fuel from the fuel nozzle to a cavity of a fuel tank, the first opening having a first axis, the second opening defining a second axis and the third opening defining a third axis, the first axis of the first opening and third axis of the third opening being coaxially aligned to define a central axis of the fuel fill passageway and the second axis of the second opening being parallel and offset relative to the first and third axes;a first plurality of longitudinal ribs;a second plurality of longitudinal ribs positioned adjacent the first longitudinal ribs, the first and second longitudinal ribs positioned in the fuel fill passageway to position the end of the fuel nozzle in the second opening of the fuel fill passageway such that a central axis of the end of the fuel nozzle is offset and parallel relative to the central axis of the fuel fill passageway and an aspirator of the fuel nozzle is positioned adjacent an inner wall of the fuel fill passageway when the fuel nozzle is inserted in the fuel fill passageway; anda deflector positioned in the fuel fill passageway adjacent an end of the first and second plurality of ribs to direct fuel vapors away from an aspirator of the fuel nozzle when the fuel nozzle is inserted in second opening of the fuel fill passageway. 2. The fuel fill apparatus of claim 1, wherein at least one of the first longitudinal ribs or the second longitudinal ribs include a lip to engage the end of the fuel nozzle when the fuel nozzle is inserted in the fuel fill passageway. 3. The fuel fill apparatus of claim 1, wherein the deflector is to direct fuel vapors away from the aspirator to prevent premature shut-off of the fuel nozzle during the fueling event. 4. The fuel fill apparatus of claim 1, further comprising a fuel cap removably coupled to the body, the fuel cap having a fluid control apparatus to allow fuel vapors to escape from the fuel tank when a pressure in the fuel tank is greater than a predetermined pressure value. 5. The fuel fill apparatus of claim 1, further comprising an inlet control valve coupled to the body, the inlet control valve to move to a closed position to prevent liquid fuel from flowing between the fuel tank and the first opening during a non-fueling event, and the inlet control valve to move to an open position to allow liquid fuel to flow to the cavity during the fueling event. 6. The fuel fill apparatus of claim 1, further comprising a lock having a flexible finger to engage a locking tab of the fuel tank to prevent the fuel fill apparatus from rotating relative to the fuel tank when a fuel cap is attached or removed from the body. 7. The fuel fill apparatus of claim 1, wherein the first opening has a first diameter, the second opening has a second diameter and the third opening has a third diameter, the first diameter being greater than the second diameter and the third diameter, the third diameter being greater than the second diameter and less than the first diameter. 8. The fuel fill apparatus of claim 7, wherein the first plurality of longitudinal ribs extend between the first opening and the second opening. 9. The fuel fill apparatus of claim 1, further comprising a nozzle retainer positioned in a throat area of the fuel fill passageway. 10. The fuel fill apparatus of claim 9, wherein the nozzle retainer protrudes from an inner surface of the first opening toward the first axis, the nozzle retainer to engage a retention feature of the fuel nozzle to retain the fuel nozzle in the fuel fill passageway. 11. The fuel fill apparatus of claim 1, further comprising a lock to prevent rotation of the body relative to the fuel tank when a fuel cap is coupled or removed relative to the body. 12. The fuel fill apparatus of claim 11, wherein the lock includes a flexible clip to engage a locking tab formed adjacent a neck of the fuel tank. 13. The fuel fill apparatus of claim 1, wherein at least a portion of the body is threaded to engage a marine tank thread. 14. The fuel fill apparatus of claim 1, wherein the body is mountable to a buttress thread or a modified buttress thread. 15. The fuel fill apparatus of claim 1, wherein the body is mountable to a 2.25 inch thread. 16. The fuel fill apparatus of claim 1, wherein the body is to removably couple to a neck of the fuel tank. 17. The fuel fill apparatus of claim 1, wherein the body is an insert mountable to a fuel neck of the fuel tank. 18. The fuel fill apparatus of claim 1, wherein the body is an insert to be at least partially positioned in a fuel neck opening of the fuel tank.
