The tank in my car does not have a vented cap. It is vented to the outside of the car through tubing that exits behind the bumper. The total height of the tank is less than 6'' high and the car sits low so I am not concerned with the center of gravity. The bracing behind the rear seat is completely sealed of with welded in panels. The tank is fabricated with 3/16'' aluminum and is totally baffled. I feel it is safer than a sheet metal tank hanging under the car.
