In a method for producing a fuel filler system, a tube shaped plastic part is introduced into a molding tool. A pressure gas pin is inserted into a first end of the plastic part. Pressure gas is introduced into the plastic part through the pressure gas pin, whereby the plastic part is expanded and adjusted to the contour of the inner walls of the molding tool. The pressure gas pin is retracted, and a constriction of the first end of the plastic part closing around the pressure gas pin is separated. A fuel filler device is inserted into the first end of the plastic part. A contact pressure is exerted, whereby a welding of the fuel filler device with the first end of the plastic part occurs. The finished plastic part is removed from the molding tool together with the fuel filler device welded therein. |
