Abstract
A fuel tank in a vehicle. The fuel tank includes a protective outer shell and an inner shell. The protective outer shell has an inner shell receiving area. The inner shell, which holds fuel, is housed in the inner shell receiving area of the outer shell. The inner shell cooperates with the outer shell to maintain the position of the inner shell relative to the outer shell and relative to the vehicle during normal operation. During an impact to the vehicle, the inner shell moves independent of the outer shell and the vehicle, allowing a portion of the energy or the forces associated with an impact to be absorbed by the outer shell, reducing the energy or force transferred to the inner shell.
