1. A fuel tank system for a vehicle, the fuel tank system comprising:
a fuel tank provided proximate frame rail members of the vehicle, a first portion of the fuel tank extending between an extension of a vertical axis of each of the frame rail members and a second portion of the fuel tank extending outside the space defined by the vertical axes of the frame rail members;
a support structure which provides impact protection to the fuel tank, the support structure having mounting members and a base plate, the mounting members mount the support structure to the frame rail members of the vehicle, the base plate extends between the mounting members;
at least a portion of the fuel tank is positioned between the mounting members and the base plate, the fuel tank being supported by the base plate;
the support structure being moveable relative to the vehicle and the fuel tank during an impact, the fuel tank being moveable relative to the vehicle and the support structure during the impact;
wherein as a lateral force is applied to the support structure, the support structure translates the lateral force to a vertical force and a lateral force, allowing the fuel tank to be moved vertically and laterally by the energy of the impact to a position in which the fuel tank is substantially out of the path of the impact or protected by the chassis of the vehicle.
