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.
