Other Fuel System Hoses Lines/piping, And Fittings problems of the 2010 Ford Mustang

My car is at the service department at planet Ford in spring, TX. I noticed a smell of gasoline and took the vehicle in for inspection when I had the passenger airbag recall done. I special ordered the vehicle in the spring of 2009 through their dealership from Ford. The vehicle currently has very low mileage, 28,000. The service manager informed me that the gas tank is coming apart at the seam and that I would need to pay $3000 to replace the tank. I called Ford customer care with my safety concerns and requested they send a representative to planet Ford to inspect the tank for defect and what may have caused it. They told me the Ford service manager at planet Ford would have to do that. When I told my service rep at planet Ford what customer care said, the Ford rep/technician denied that they could do that and offered me know further help with escalating my concerns to Ford. I want Ford to see if there was something different with my custom order at their factory that caused it? I want Ford to come and see what they built and sold me and to note the safety hazards to my life. I understand it's not under warranty. It makes no sense to me that the shrapnel in their defective airbags were more important to them than a defective gas tank that's coming apart at the seam and off-gassing badly. The gas fumes are very toxic and volatile and could cause an explosion or give me cancer. For the longest time, I thought the fumes were normal, since that Mustang has the cap-less gas tank and I was associating the odor near the rear area where I filled-up. It took friends and family telling me 'no, that smell is not normal. " and that it urgently needs to be assessed.
