Abstract
A misfuelling prevention device for a filler neck of a fuel tank includes a tubular element with an inflow side and an outflow side and a closure element, which, when in an open state, permits a flow of fuel through the outflow side, and, when in a closed state, prevents a flow of fuel through the outflow side. In a shell surface of the tubular element there is formed at least one opening which permits a flow of fuel from an inner side of the tubular element through to an outer side of the tubular element. The tubular element can be mounted such that at least a part of the shell surface in which the at least one opening is formed is arranged spaced apart from an inner surface of the filler neck such that fuel flowing through the at least one opening can flow via the filler neck into the fuel tank.
