A fuel tank system includes a fuel tank and a support structure. The support structure provides impact protection to the fuel tank. The support structure has mounting members, a bottom plate and a support member. The mounting members mount to the vehicle. The bottom plate is provided proximate a bottom wall of the fuel tank, wherein the bottom plate protects the fuel tank from being crushed or punctured and serves as a skid plate if ground contact is made. The support member extends between a respective mounting member and the bottom plate. The support member is configured to fail during impact, allowing the fuel tank to be moved downwardly 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.

1. A fuel tank system for a vehicle, the fuel tank system comprising: a fuel tank;a support structure which provides impact protection to the fuel tank, the support structure having mounting members, a bottom plate, and a support member, the mounting members mount to the vehicle, the bottom plate pr
1. A fuel tank system for a vehicle, the fuel tank system comprising: a fuel tank;a support structure which provides impact protection to the fuel tank, the support structure having mounting members, a bottom plate, and a support member, the mounting members mount to the vehicle, the bottom plate provided proximate a bottom wall of the fuel tank, wherein the bottom plate protects the fuel tank from being crushed or punctured and serves as a skid plate if ground contact is made, the support member extending between a respective mounting member and the bottom plate; andwherein the support member is configured to fail during an impact, allowing energy applied during the impact to the support structure to be translated to a vertical force and a lateral force, pushing the fuel tank in a direction which is lateral to the direction of a longitudinal axis of the frame rail members and perpendicular to the direction of the longitudinal axis of the frame rail members, 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 into a vertical force and a lateral force. 2. The fuel tank system of claim 1, wherein the fuel tank has sloped walls which extend from a top wall positioned proximate the vehicle. 3. The fuel tank system of claim 1, wherein portions of the mounting members are sloped. 4. The fuel tank system of claim 1, wherein the mounting members have nonlinear cross-sections to provide additional strength to the mounting members. 5. The fuel tank system of claim 1, wherein the bottom plate has a leading edge which is turned up to allow for protection of the fuel tank. 6. The fuel tank system of claim 1, wherein a guard is positioned between the fuel tank and a drive shaft of the vehicle to provide protection of the fuel tank in the event of a failure of the drive shaft. 7. A fuel tank system for a vehicle, the fuel tank system comprising: at least one fuel tank provided proximate frame rail members of the vehicle, the at least one fuel tank having a top wall positioned proximate a drive shaft of the vehicle, a first portion of the at least one fuel tank extending between an extension of a vertical axis of each of the frame rail members and a second portion of the at least one fuel tank extending beyond the vertical axis of each of the frame rail members;a support structure having mounting members which are mounted to the frame rail members, the support structure provides impact protection to the at least one fuel tank;a plate provided proximate a bottom wall of the at least one fuel tank, wherein the plate protects the at least one fuel tank from being crushed or punctured and serves as a skid plate if ground contact is made;a support member extending between a respective mounting member and the plate, the support member configured to fail during an impact; andwherein a lateral force applied during the impact to the at least one fuel tank or the support structure will be partially translated to a vertical force and a lateral force, causing the at least one fuel tank to be moved in a direction which is both lateral to the direction of a longitudinal axis of the frame rail members and perpendicular to the direction of the longitudinal axis of the frame rail members, allowing the at least one fuel tank to be moved vertically and laterally by the energy of the impact to a position in which the fuel tanks are out of the path of the impact or protected by a chassis of the vehicle. 8. The fuel tank system of claim 7, wherein the at least one fuel tank is adapted to be horizontally attached to the underside of the vehicle, such that the top wall of the at least one fuel tank is essentially parallel to a horizontal plane of a longitudinal axis of the frame rail members and essentially parallel to a longitudinal axis of the drive shaft. 9. The fuel tank system of claim 7, wherein portions of the mounting members are sloped away from the respective frame rail member to which the mounting members are attached, wherein the portions of the mounting members are configured to push the at least one fuel tank to be moved away from the frame rail members in response to the impact applied to the support structure. 10. The fuel tank system of claim 9, wherein the mounting members have nonlinear cross-sections to provide additional strength to the mounting members. 11. The fuel tank system of claim 7, wherein the plate has a leading edge which is turned up to allow for protection of the at least one fuel tank. 12. The fuel tank system of claim 7, wherein a guard is positioned between the at least one fuel tank and the drive shaft to provide protection for the at least one fuel tank in the event of a failure of the drive shaft. 13. The fuel tank system of claim 7, wherein the support structure includes rails mounted to the mounting members, the rails having a nonlinear cross-section to provide additional strength to the rails which provides integrity to the system and provides crush resistance for the fuel tank, the nonlinear cross-section of the rails allowing for forces applied to the rails to be dissipated over a surface of the rails, thereby protecting the tank from the energy of the impact. 14. A fuel tank system for use with a motor vehicle, the fuel tank system comprising: a fuel tank provided proximate frame rail members of the motor vehicle, at least 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 beyond the vertical axis of each of the frame rail members, the fuel tank having a top wall positioned proximate a drive shaft of the vehicle;a support structure having mounting members which are mounted to the frame rail members and which position the fuel tank proximate the frame rail members, the support structure protects the fuel tank during an impact; anda plate is provided proximate a bottom wall of the fuel tank, a support member extends between a respective mounting member and the plate, the support member is configured to fail during the impact, allowing the fuel tank to be moved vertically and laterally of a longitudinal axis of the frame rail members 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. 15. The fuel tank system of claim 14, wherein respective mounting members are positioned on either side of the fuel tank, each respective mounting member being a one piece member which extends along an entire side of the fuel tank. 16. The fuel tank system of claim 14, wherein the support structure includes rails mounted to the mounting members. 17. The fuel tank system of claim 16, wherein the rails having a nonlinear cross-section to provide additional strength to the rails which provides integrity to the system and provides crush resistance for the fuel tank, the nonlinear cross-section of the rails allowing for forces applied to the rails to be dissipated over a surface of the rails, thereby protecting the fuel tank from the energy of the impact.
