| 摘要 |
Transition conduit piping arranged between an underground fuel flow pipe and an above-ground fuel pumping unit, includes a forty-five degree elbow attached to the side wall of a liquid spill-containment casing and a semi-flexible hose connected between the underground flow pipe and the forty-five degree elbow. Orientation of the transition piping is such that conduit pipe joints are readily accessible for observation or repair of leaking joints. The invention avoids earth contamination problems associated with undetected underground gasoline leaks.
