Fuel Delivery problems of the 2003 Mazda MAZDA6

2003 Mazda 6 recall 1403l, campaign # 03v531000, on my vehicle supposedly was repaired in baton rouge at diamond Mazda in 2004, but car is leaking in the same area that was a problem to begin with now. So the workmanship where they repair the seal is not very good. Four years later I buy the car and it is poor gas on the top of my gas tank out of the seal around the fuel pump which just happens to be right under where my child sits. So I've been in a time bomb just waiting to go off. No one can give me proof or paper work of where this recall has been taken care of. Now suppose that it did blow up and kill or injure myself and my 3 year old daughter. Wouldn't Mazda be at fault for not properly repairing the vehicle?.
