IMPROVED FILLER NECK

摘要

An insert for location in a filler neck (10) for a fuel tank, the insert comprising a blocking member (18), a mounting arrangement for mounting the blocking member in the neck and an elongate member (16) connecting the blocking member to the mounting arrangement. The mounting arrangement being adapted to connect to the filler neck in the region of the open end of the filler neck, such that when the insert (100) is located in the filler neck, the blocking member is positioned substantially at a mouth of the filler neck to prevent a fuel filling nozzle being inserted in the filler neck except where the filling nozzle has an internal bore size sufficient to allow it to pass over the blocking member.
