If you look at a typical filling station, there's only one set of pipes
the tankers connect to, in order to unload. That means the model of "one
tank per pump" is simply a misunderstanding.
Here's the unloading bay at Tesco, Ely:

three flavours at each pump suggests they have two sets of tanks, for
servicing the six double-sided pumps. That's perhaps how sometimes one
pump will have run out, while another still has supply.
