Couple weeks ago the flapper on my filler neck broke and has went into the tank im assuming. I have gotten a filler neck off ebay that was from a 10 model, it didn't have the flapper either, so I contacted the seller and he said non of the focus he had on his yard had the flapper. All was 10 & 11 models, so then I ordered via the part # from a ford parts site and it is missing the flapper too. I looked on fordparts.com and it listed the same part # but for two different build dates. Was there actually focus built out there that doesn't have the flapper on the fuel neck. I just wanna make sure im not losing my mind. Any clarification on this would be helpful. Thanks!
