No I'm talking about at the individual stations. There are hand or battery operated pumps that could easily fuel trucks for refueling places like cell towers or other critical places with generators.
Ah I see what you are getting at, you'd use the drop ports to pump fuel out. That works as long as they are not buried too deep, and no gas station owner would let you submerge a pump to push up.
A typical station has anywhere from 50K to 1M liters of underground capacity so that should be enough for a bit, if their own pumps aren't running then they will likely be happy to be able to sell some of it.
