ABSTRACT:
A vent device connectible in a fill pipe of an underground fuel storage tank having a cylindrical housing with a drop tube and a J-shape tubular fitting with two open ends. The first open end is open within the drop tube and directed toward the underground fuel tank and the second open end is exposed through the wall of the cylindrical housing into an upper portion of the underground fuel storage tank. The tubular fitting has an expansion chamber vertically disposed between the two open ends for holding a float ball therein. The float ball is confined within the expansion chamber by a lower seat of the chamber and a barrier extending across the diameter of the chamber to prevent the float ball from sealing the upper seat of the chamber. Gaseous and liquid fluid may enter the first open end and flow through the second open end to the upper portion of the underground fuel storage tank; but the float ball blocks the first open end so gaseous and liquid fluid cannot enter into the drop tube from the upper portion of the underground fuel storage tank.
