Abstract

A filler-tube assembly for a fuel tank has a filler tube having an upper end formed by a tubular inner wall defining a fill passage and having an outer surface and a concentric outer wall fixed relative to and defining with the inner wall an annular and upwardly open space and having an inner surface and an end surface. A cap adapted to fit over the outer end has a tubular extension fittable in the space and having inner and outer surfaces and an end surface bridging the respective inner and outer surfaces. A seal ring in the space is engaged between one of the surfaces of the cap and one of the surfaces of the filler tube.
