When replacing a gas tank on a Chevy Lumina your gonna need a screwdriver and a jack. The gas tank is located in the rear drivers side of the car. First make sure the gas tank is empty. Next use the jack to raise the car. When the car is raised you will have a visual of the gas tank. There are three straps on the tank that will unscrew and free the tank. Replace and reassemble.
