Abstract: A vacuum regulated fluid delivery system is disclosed. The fluid delivery system may have a cap configured to receive a closed reservoir of fluid. The cap may have first and second openings extending from the cap. The first opening may have a first external nozzle for carrying water or other fluid from the closed reservoir to an open reservoir. The second opening may have a second external nozzle for allowing air to flow into and out of the first reservoir. The fluid delivery system may also have a tube terminal unit having first and second openings. The first tube terminal opening may have a first nozzle connected to the first external nozzle of the cap by a flexible tube for receiving water or other fluid from the closed reservoir and delivering it to an open reservoir out a fluid delivery outlet.
