The invention relates to a method for the riveted fastening of an accessory to a plastics fuel tank (), the riveted fastening taking place at the time of the production of the tank by extrusion blow-molding of a split tubular preform or two web-like extruded preforms made of thermoplastic material by using a multi-part die after or during the molding of two complementary shells. The accessory () has been provided or is provided with at least one opening. The method according to the invention is characterized in that the riveted fastening takes place by means of at least one prefabricated rivet pin () made of thermoplastic material. The rivet pin has been obtained in a separate production process, for example by injection-molding.

Method for the riveted fastening of an accessory

Functional components which are stationarily mounted in a fuel tank and connected together by way of a connecting line can be damaged by a change in size and shape of the fuel tank. The invention concerns a fuel tank, in particular of thermoplastic material, comprising at least two functional components such as for example venting valves, pumps, containers or the like, which are stationarily arranged in a fuel tank and which are connected together by way of a connecting line. To avoid damage, in accordance with the invention one connecting line includes at least a first portion and a second portion, wherein the stiffness of the first portion is less than the stiffness of the second portion.
