Other Fuel System Hoses Lines/piping, And Fittings problems of the 2016 Ford Fusion

I found a fuel leak on my 2016 Ford Fusion titanium ecoboost. About 5 months ago when I first notice the problem, a smell of fuel on the left rear passenger side door and as you go further to the rear,the smell of fuel gets stronger, I went to the ground to check for any sign of leaks but I never found any, except for the strong scent of fuel. I thought it was just a fuel thats coming from the fuel refill cap and didnt pay much attention to it. Not until after coming back from work,about 5 months later and went to tend for my vehicle that were parked in our drive way for 5 months, as I sat down on the driver seat and start the engine, I notice the gas on the tank, it was 1/4 left but prior from leaving the vehicle at the drive way, I refuel it and left it with a full tank, so I went around my vehicle to investigate the under carriage of the car and ended up seeing a stain of fuel leak on the ground and as I went deep down under the vehicle were the tank is located, I start to see a trace of fuel dripping down from the gas tank and to the tank shield or tank cover?! I cant named the plate that holds the fuel tank and as I trace it further to the gas tank I saw were the leak is coming from and its coming from were the refill tube was installed. . ! I start to check the web for any clues on what could cause it from getting a crack on the tank and found that Ford Fusions had recalls for the same car, same brand, same year but different manufactured month date but same on the manufactured year wich is 2015 and still Ford motor company denies a factory deffect and wont grant me a recall that were made at the same year, brand,model but different manufactured month. . I hope that someone could adress this issue and get the problem fixed specially when a problem involves a fuel, it is very serious not only for safety of the motorist but to endanger our ecosystem as well. . .
