Abstract

A fuel closure assembly is especially useful in multi-layer fuel tanks. An opening in a fuel tank wall having an externally threaded nipple forms a planar sealing surface. An seal is centered about a radial surface of the nipple. A plate closes the opening and is retained in position by a threaded ring.
