A device, system and/or method for dispensing a fuel additive to a fuel tank that employs a fuel additive delivery device secured to an opening of the fuel tank. The delivery device is fluidly coupled to a fuel additive reservoir. The delivery device includes a cap that automatically opens or closes fluid communication with the fuel additive reservoir. The delivery device also includes a bore defined through the delivery device configured to receive a fuel filler spout with a fuel passageway outlet positioned in the bore such that, as fuel passes through the bore and into the fuel tank, the bore is configured to create a suction at the fuel additive outlet to pull fuel additive from the reservoir, through the delivery device, and into the fuel tank with the fuel.

The system of claim 1, wherein the fuel additive delivery device is configured to sealingly connect to the opening of the fuel tank. 3. The system of claim 1, wherein the fuel additive delivery device comprises one or more air passageways defined therein, each passageway extending through the delivery device between a first end and a second end of the passageway such that, upon the cap being removed from the upper opening, the first end is positioned on the delivery device so as to be above the fuel tank and the second end is positioned to be within the fuel tank. 4. The system of claim 1, wherein the container comprises a conduit extending to the fuel additive passageway defined in the fuel additive delivery device. 5. The system of claim 1, wherein the bore comprises a nozzle defined therein with a narrow neck configured to manipulate a pressure of fluid passing through the nozzle. 6. The system of claim 5, wherein the fuel additive passageway comprises a fuel additive outlet adjacent the narrow neck of the nozzle so as to facilitate the fuel additive to be drawn from the container as fuel passes through the nozzle. 7. The system of claim 6, wherein the container is positioned adjacent the fuel additive delivery device such that, upon the plunger being in the open position, the fuel additive advances through the fuel additive passageway by a combination of influences of gravity and being drawn from the container. 8. The system of claim 1, wherein the fuel additive passageway extends through a portion of the fuel additive delivery device between a fuel additive inlet and a fuel additive outlet, the fuel additive inlet is configured to receive the fuel additive from the container and the fuel additive outlet is configured to be exposed adjacent a narrow neck defined in the bore of the delivery device. 9. The system of claim 1, wherein the container is positioned adjacent the fuel additive delivery device such that, upon the plunger being in the open position, the fuel additive advances through the fuel additive passageway by gravity. 10. The system of claim 1, wherein the spring biased plunger comprises a blocking portion and a bypassing portion, the blocking portion configured to block the fuel additive passageway upon the spring biased plunger being in the closed position, and the bypassing portion being sized smaller than the blocking portion so as to facilitate the fuel additive to advance upon the plunger being in the open position. 11. The system of claim 1, wherein the delivery device comprises a tapered surface and tab arrangement configured to seal and mount the delivery device to a fuel tank. 12. A fuel additive delivery device configured to dispense a fuel additive into a fuel tank from a fuel additive container, the device comprising: a structure configured to be connected to an opening of the fuel tank, the structure defining a bore extending therethrough and a fuel additive passageway extending through the structure and to the bore, the bore extending between an upper opening and a lower opening of the structure, the structure configured to be positioned around the opening of the fuel tank with the lower opening disposed within the fuel tank;a spring biased plunger including an elongated structure and a spring, the elongated structure positioned adjacent the upper opening and moveable within the fuel additive passageway between an open position and a closed position, the open position configured to facilitate the fuel additive to advance from the fuel additive container through the fuel additive passageway and into the bore of the structure; anda cap configured to be positioned over the upper opening of the structure so as to prevent fluid from entering the fuel tank and to maintain the spring biased plunger in the closed position such that the elongated structure directly blocks the fuel additive passageway, and, upon the cap being removed from the upper opening, the spring biased plunger being biased toward and moved to the open position. 13. The fuel additive delivery device of claim 12, wherein the structure is configured to sealingly connect to the opening of the fuel tank. 14. The fuel additive delivery device of claim 12, wherein the structure comprises one or more air passageways defined therein, each passageway extending through the structure between a first end and a second end of the passageway such that, upon the cap being removed from the upper opening, the first end is positioned on the delivery device so as to be above the fuel tank and the second end is positioned to be within the fuel tank. 15.
