There is provided a liquid level sensor apparatus that has particular and beneficial application in a fuel tank, such as a saddle-tank used in automotive vehicles comprising first and second fuel compartments. The liquid level sensor apparatus is for determining a level or quantity of fuel therein. The liquid level sensor apparatus comprises means for issuing an electrical signal indicative of a level or quantity of liquid, such as a sender unit comprising a motion-responsive potentiometer. Additionally there is provided a first float assembly that is moveable in response to a first liquid level. The first float assembly is coupled directly to said means such that in response to movement of the first float assembly an electrical characteristic of said means is affected and an electrical signal issued by said means is indicative of said first liquid level. Furthermore, there is provided a second float assembly that is moveable in response to a second liquid level. The second float assembly is indirectly coupled to said means and in such a way that in response to movement of the second float assembly an electrical characteristic of said means is affected and an electrical signal issued by said means is indicative of said second liquid level.

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.

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.
