Hi, my name is Michael. I will be able to help you with the repair/replacement of the gas tank. Are you aware that the fuel pump and level sensors are accessed from the bottom of the car? If there is a leak from the top of the tank, you won't be able to access it from under the seat like on other models. The whole tank will have to be drained and lowered. This process involves removal of the rear axle subframe and special equipment. It is possible to lower the fuel tank enough to view what is leaking on the top but you may not have enough clearance to repair any leaks. Are you under the assumption you can access the top of the fuel tank from under the rear seat?
