A method and system for preventing vehicle misfueling by utilizing an apparatus (300) that receives a fuel nozzle into the filler neck (302), and activates a vacuum on the nozzle inserted therein. Using the pump~s internal shut-off mechanism, this prevents the fuel pump from dispensing fuel until the sensing unit (310) within the apparatus (300) is able to identify the fuel proposed to be added to the tank. If the fuel is deemed acceptable, the vacuum is released, and the fuel is permitted to enter into the desired fuel tank.

L'invention concerne un procédé et un système destinés à empêcher le méremplissage d'un véhicule grâce à l'utilisation d'un appareil (300) qui reçoit un pistolet de remplissage dans le goulot de remplissage (302) et actionne une pompe à vide sur le pistolet inséré. Grâce à l'utilisation du mécanisme d'arrêt interne de la pompe, on empêche toute distribution de carburant jusqu'à ce qu'une unité de détection (310) faisant partie de l'appareil (300) soit capable d'identifier le carburant qu'on a l'intention de verser dans le réservoir. Si ce carburant est jugé acceptable, le vide est débloqué, et le carburant peut couler dans le réservoir choisi.
