A fuel tank assembly includes a hinge assembly, a fuel tank, and at least one hinge bolt. The hinge assembly includes a hinge pin and a hinge stay. The hinge pin pivotally couples the hinge stay to a vehicular frame and defines a hinge axis about which the hinge stay is pivotable with respect to a frame. The at least one hinge bolt releasably couples the hinge stay to the fuel tank such that the fuel tank is pivotable about the hinge axis. The at least one hinge bolt intersects the hinge axis and obstructs the hinge pin from being removed from the hinge stay.
