Abstract
A fuel tank in a vehicle. The fuel tank includes a protective outer shell, an inner shell and a crush sleeve. The protective outer shell defines an outer tank. The inner shell defines an inner tank which holds fuel. The inner shell is housed in the outer shell and is isolated from the outer shell by a space. The crush sleeve is provided in the space between the outer shell and the inner shell. The crush sleeve supports the inner shell and maintains the inner shell in position relative to the outer shell. Wherein during an impact to the vehicle, the force of the impact causes the outer shell and the crush sleeve to deform and the inner shell to move relative to the outer shell.
