Abstract
An apparatus for repairing an existing spill containment manhole operably associated with an underground fuel storage tank. The apparatus includes a containment vessel for containing fuel spilled during filling of the underground fuel storage tank. A major portion of the containment vessel is adapted to be inserted into an existing spill containment manhole. Preferably, the containment vessel includes an upper annular flange that extends over and surrounds a portion of an existing cover rim of an existing spill containment manhole thereby isolating an upper portion of the containment vessel from an upper portion on the existing spill containment manhole when the containment vessel is installed. Optionally, a replacement cover is provided to replace an existing cover of the existing spill containment manhole. The replacement cover may include at least one sealing member that engages the inner surface of the at least one wall of the containment vessel when installed.
