Abstract
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.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
138 words
An improved non self-propelled portable fueling facility comprising: storage tank means for storing fuel; outer tank means for providing secondary containment about said storage tank means; means for supporting said outer tank means on an underlying surface wherein said means for supporting includes a fixed lower surface for engaging the underlying surface; pump means adapted for dispensing fuel into an aircraft or the like; supply pipe means for guiding fuel from said storage tank means to said pump means; and deck compartment means for supporting said pump means with respect to the underlying surface, said deck compartment means being connected to said outer tank means, and having a compartment defined therein through which said supply pipe means extends, whereby the area around said supply pipe means is protected from incidental spillage which could result in contamination or combustion.
Claim 2
Dependent Claim
138 words
