An overfill assembly for use with storage tanks, especially underground gasoline storage tanks. The overfill assembly comprises a dump tank with a fill pipe mounted therein. The fill pipe extends through the dump tank's bottom and is in communication with the storage tank. A removable center-point compression sealing lid member for the dump tank allows for ready access to the fill pipe. A valve mechanism in the dump tank allows for controlled emptying of spilled liquid in the dump tank to the storage tank.
