Abstract
A fuel tank (1) possesses, for the introduction of fuel, a filler pipe (5) which is led through an orifice (6) of the fuel tank (1) with all-round clearance. The orifice (6) is sealingly closed by means of a sleeve (4) bearing against the fuel tank (1) and against the filler pipe (5). The orifice (6) can thereby be made relatively large, so that it can be additionally used also as a service or assembly orifice after the sleeve (4) has been removed. The number of orifices necessary on the fuel tank (1) can be reduced as a result, so that both the maximum filling quantity and the permeation tightness can be increased.
