Abstract: An overfill and spillage protection device for capturing fuel spilled from a tank touch supply hose or the fill pipe of an underground fuel storage tank takes the form of a tubular reservoir having an axially flexible bellows shaped side wall. Forces induced by freezing or thawing of the ground in which the reservoir is embedded which would apply strain to the coupling between the reservoir and fill pipe are absorbed by the flexing action of the bellows shaped reservoir. A rigid tubular skirt slidably encloses the bellows portion to prevent concrete or dirt from packing into the concave regions of the bellows.

Abstract: A breakaway hose coupling includes axially separable housing sections maintained in coupled relationship with each other by a frangible coupling pin or set screw. Each housing section includes a valve controlled flow passage in which a spring biassed valve closes the flow passage when the housing sections are separated. Valve stems on the respective valves moves into axial abutment with each other as the housing sections are coupled to mutually hold the respective valves open when the housing sections are coupled.

Abstract: A locking lid assembly for sealably closing the upper end of a cylindrical stack of a fuel spillage capture recovery device includes a lid hingedly mounted on an annular base member constructed to be sealingly seated upon the top of the stack. Diametrically opposed pivoted cams mounted on the lid are wedgingly engageable with locking pins mounted on the base member to firmly compress a resilient annular seal between the lid and base member.
