Structures 19A–D were for gasoline storage and distribution. Delivered by tank car at four unloading points on a special railroad siding, and by gasoline trucks at four additional points, the gasoline was stored in four underground pre-stressed reinforced concrete tanks that were lined with Thiokol. Three of the tanks had capacity and were used for 73 octane gasoline. The other was a tank used for 100 octane gasoline. The fuel was pumped to distribution points through two separate piping systems, one for 73 octane and one for 100 octane, by two submerged type multiple stage centrifugal, , pumps at each tank; each pump powered with a electric motor. Distribution points for 73 octane gasoline consisted of a tank truck filling stand, 200 gpm, and 56 gasoline servicing pits for fuelling planes directly, located at the warmup aprons, with capacity to fuel 48 planes simultaneously at the rate of per plane. The 100 octane gasoline, the tank truck filling stand was capable of , and four planes could be fueled at a rate of . The system included of diameter welded steel pipe. The 100 octane system was actually used for 87 octane gasoline with 100 octane being provided by a later contract.
