a. I'd lay odds that the tank got turned. the mid-level vent was supposed to be center top. Someone turned it so that they could use one of the end fittings as a drain, instead of installing a proper drop tube. Could have been Bristol or PO. Flipping the tank back to the proper position and re-piping would have solved most of the problem.
b. Looks like a pump would fit to me.
And I think I would have gone for a larger tank. Different shape.
