Patent ID: 7997307

Claim:
An apparatus for positioning a fill nozzle comprising: an elongated fill pipe assembly; an annular seal operatively connected within the fill pipe assembly and defining a center aperture; wherein the seal is sized to seal around the fill nozzle; a first annular restriction within the fill pipe assembly and defining a first aperture; a second annular restriction within the fill pipe assembly and defining a second aperture; wherein the first and second apertures are sized to sufficiently restrict lateral movement of the fill nozzle within the fill pipe assembly to maintain sealing contact of the annular seal around the fill nozzle; wherein the annular seal is formed with an angled lip that extends radially inward; wherein the second annular restriction is formed on a retaining member; wherein the retaining member defines a circumferential channel radially outward of the second annular restriction; wherein the annular seal has a retention portion radially outward of the lip; and wherein the retention portion is nested within the channel with the retaining member surrounding the annular seal both radially inward and radially outward of the retention portion.
