Most later model vehicles have in tank pumps. So if a vehicle like this had two tanks it would stand to reason that it would have two pumps. But vehicles that I have been associated with that had two tanks had only one external pump. the way i could tell was the way the tanks were switched. If the switch for switching tanks is an electrical switch then there are probably two in tank pumps. The ones I have been associated with had a ball valve switch that was in a copper line which just directed the flow from the different tanks to the pump on the engine. This is a little vague but hopefully it may help.
