The inlet unit (4) to be welded to a fuel tank consists at least in parts of polyethylene which as been irradiated with high-energy electrons or gamma rays. An Independent claim is also included for a method of joining an inlet unit to a fuel tank involving irradiating at least parts of the inlet unit with high-energy electrons or gamma rays before welding is undertaken.
