Abstract: An improved portable fueling facility for aircraft or ground vehicles includes at least one storage tank, an outer tank for providing secondary containment about the storage tanks, a number of saddle members for supporting the outer tank on a flat horizontal surface and at least one pump for dispensing fuel. A deck compartment is provided beneath the pumps for providing secondary containment about the supply pipes which are used to supply the pumps and the refueling tubes which are used to refuel the storage tanks. The entire facility is portable, so that it may be redepolyed at different locations or airports as needed. According to one novel aspect of the facility, a control system is provided which permits self-service use of the facility in a manner which requires only the use of a commercial credit card.
