soo hers the deal, my girlfriends 05 focus st just had its gas cap light come on. now cmon guys i already checked to make sure the cap was tight. lol. But anyway i took the cap off, and realized there isnt a little tab in there. usually when you put the gas nozzle in, it pushes the metal tab open, but there isnt one. my question is did it not have one before or did it fall intothe tank and thats the problem???
