I replaced a power steering pump in an Acura TL 2005, connected the inlet hose, and the outlet hose, but the new pump did not come with a bolt on the bottom similar to the one shown in the photo of my old pump. Any ideas about what this recessed bolt is actually called and which tool I would need to get it out and install it in the new pump? Thanks.
That's the flow control valve cap. If your new pump doesn't have it, I would assume it's designed that way (or are you saying that the new pump has an opening in the same place with no plug?). To remove that, you'll need a large Allen wrench, or preferably, a hex socket.

In place of the flow control valve cap, the new pump has an opening with no plug. The other two openings had plastic caps that I removed, but this one didn't. I don't think I misplaced it so I might have to take the cap out of the old pump.
OP, I think you're looking at this wrong. The reman pump should only have caps on the inlet and outlet ports, and the shaft. The reman pump (as pictured on the AZone site) does indeed have the flow control valve cap already installed (circled in red). The blue cap shown facing us is in the inlet port:

Thanks for the detailed diagram -- I was working off the less detailed diagrams before this part of the service manual. I think you're right. The flow control valve cap is probably on the new one. I just can't see it under the pump because it's already installed.
The old pump was leaking near the pump cover seal, which I found by using a UV dye. So I flushed the fluid a couple of times and installed the new pump but there are a lot of air bubbles in the reservoir and a leak under the inlet joint. Bleeding on two occasions with the engine off didn't help. Same hoses but new clamps are on tight. I replaced the outlet o-ring (on top) but wasn't aware of the inlet o-ring -- will replace to see whether it's the problem. If this doesn't work, guess I'll try the dye again.

Water under the bridge now, but you may have only needed to replace the cover seal.
And yeah, the inlet O-ring is the one that is notorious for air leaks...
