Gasoline Storage problems of the 2005 Lincoln LS

I noticed what I thought was an exhaust leak on the interior of my 2005 Ls, so I raised the hood didn't smell anything. I did however notice that their was oil spots in my driveway. I took the car immediately to the repair shop and had the top half of the engine resealed. Two days later I started the car and after letting it warm up; I got in and the smell was still there. I took it back and after 4 hours of labor the sniffer alarm sounded on the fuel tank. While searching for a repair the mechanic discovered the Ford recall notice 05s29, NHTSA campaign id number : 05v113000. So I went my Lincoln dealer and they told me that there was "no recall notice for a leaking fuel tank for the Ls. " not satisfied I took my repair documentations to a Ford dealer, and they stated that there was a recall, but my car was not included. Note: this is where I really got ticked off. There is a recall for the problem I have, but because the research was improperly performed I need to pay Ford $1600 to replace a tank that would otherwise be free. It's obvious that the research is faulty. . .
