Beta Systems Pump Assembly

I found this fuel pump system at the Oregon State surplus property sales.  This unit would be mounted on a 2.5 ton truck with a pair of 500 gallon fuel tanks.  This unit operates on 24 volt.

Any idea when these were in use?
I wonder how they powered them? The Inters were all 12 volt. Maybe the later Unimogs or Macks ran 24 volt systems.
It would have to be fitted to a 5 ton or higher truck as 2x500 gallon tanks would weigh over 4.5t when full.

They are US equipment what do they use?

They were in service during the 1980-90s.  When my infantry company went to the field for training, we would use these mobile fuel stations to fill up and continue on to our training area.  Booger is correct, this is US equipment and every vehicle I had experience with in the US Army was 24 volt.  I was guessing at the 2.5 ton truck but you must be correct about the size of the vehicle.  This unit uses an electrical pump and could be powered directly from the vehicle or it could be powered by 24 volt generator.  From looking at the manual, it appears there was a mechanical (gas/diesel) engine powered unit.
