Where can I get a mechanical fuel pump for a 1969 1600 roadster (or a rebuild kit)? I tried Dealer=NA; O'Rielly, Auto Zone, Pep Boys = no listing. RockAuto had a listing ( BWD/NIEHOLL #41453, ordered one and it was not even close. ( It looks like the one for a Nissan 510 AIRTEX # 1069.) It will be going back. Thanks, Mike
