Thanks for the info. The part# of the filler pipe for N20 and N26 are different(16117244035 and 16117270991), need to find another N26 to check. From the look of it, the N26 metal flap looks like a switch rather than a cover for the filler pipe opening. I now wonder if the N26 fuel tank is sealed(to achieve zero evaporative emission), and this switch opens up the tank during fillup?
