Here is the tag that is on the pump:

I maybe mistaken, but I believe that your pump is not a two stage pump, but
a "tandem" pump. Simply two pumps in one assembly. In you picture the
fitting on the right is the inlet port that would go to the tank, and the
two ports on the left or both discharge ports.

That was my guess as well.
