Other Fuel System Hoses Lines/piping, And Fittings problems of the 2011 Ford Fusion

Had been having issues with my 2011 Ford Fusion since early 2015. Each time I put fuel into the vehicle, the vehicle wouldn¿t start ¿ similar to what happens when engine is flooded. Thought it was bad fuel. Ran the fuel tank to nearly empty and refueled. Same issue every time I refuel. Made sure there was nothing blocking the fuel filler cap/flap. Check engine light would go on and off and then stayed on. In sept 2015, took vehicle to a certified mechanic and the error codes (po456 and po104) indicated a problem with the fuel/propulsion system. Replaced purge solenoid. Did not fix the problem. Received recall notice 15s34 in January 2016 related to a defect/safety issue with the fuel system & fuel tank. March 2016 (engine light still on) took vehicle to Ford dealer and explained the problems I¿ve been having and provided bill from mechanic and documentation found of other Ford owners having the same issues. Dealer inspected vehicle & said everything was fine except that I have a leak in my fuel filler neck which is not part of the recall, but they could replace ¿for about $250 or so¿. How is it that this not included in the recall? fuel and fumes leaking from the filler neck are as dangerous as cracks and leaks in the tank. Did some research and this seems to be a common problem that Ford has been made aware of. There is no reasonable explanation as to how I would have cracked the fuel filler neck. The car only has approx. 66k miles on it, was bought brand new in 2010, is regularly serviced and has never been misused. Contacted Ford and was advised that they would "note" my safety concerns in their case (cas-9098523). Nhtsa needs to look into this and force Ford to take corrective measures.
