First, fuel tanks don't have an overflow. If you are leaking gas, my guess is the steel fuel lines from the fuel tank to the engine are rusted and leaking. That would also explain the poor fuel mileage. Chech the fuel lines. If everything is good, you may need to remove the fuel tank to check for a rusted sending unit or tank.
Let me know what you find. Also, keep in mind that any fuel leak is dangerous.
