An overfill prevention device is provided for preventing overflow of a fluid storage tank. The overfill prevention device includes a filler cup designed to fit within the fill opening of the tank body and attach thereto. A seal that is adapted for receiving and sealing to a fill nozzle is placed between upper and lower regions of the filler cup. A breather piece, which defines a vapor path with first and second openings, is integrated with the filler cup. The first opening of the breather piece is fluidly coupled to the lower cup region, whereas the second opening is positioned above the first opening, located at or below the full level of the storage tank. |
