Abstract: A fuel bag kit comprising a inflatable/deflatable fuel bag for storing fuel therein. The inflatable/deflatable fuel bag comprises a rubber bladder having a deflated/collapsed state to define a deflated/collapsed outer perimeter contour when the rubber bladder is essentially empty and a inflated/expanded state to define a inflated/expanded outer perimeter contour when the rubber bladder is filled with fuel. The deflated/collapsed outer perimeter contour has a significantly thinner width than the inflated/expanded outer perimeter contour. The fuel bag further comprises a nozzle removably coupled to a top end of the rubber bladder and a handle coupled to a bottom end of the rubber bladder. A fuel bag storage container having an outer perimeter contour which is dimensioned smaller than the rubber bladder in the inflated/expanded state and which stores therein the inflatable/deflatable fuel bag when said rubber bladder is in the deflated/collapsed state.
