threaded pump fitting letting in some air

If you have confirmed that there are no cracks or broken pieces, I might have an idea. It looks like your 2 ball valves come apart. I have several like them, but I have never taken them apart so I don't know how they fit together. Without knowing that, my idea would be to dig down as far as you can to give you some play in the vertical pipes that go in the ground, loosen the quick fittings on the valves, detach what you can from the pump so you can pick it up ot tilt it a little and screw in what's remaining or replace it.

the problem isn't that i can't access the pipes entering the pump to tighten/loosen. that's no problem, since i can just detach the pipes at the ball valves. the problem is that because of the piping having to line up, i can't screw the whole mess into the pump quite tight enough.

I see now what you are saying. I would say you have 2 choices, live with the air ni the line, or rebuild. If you choose to rebuild, hopefully you can save the ball valves. They are so expensive that I always try to put in shut off and check valves in a way that I can salvage them in the event of a future rebuild. In you case, you really don't have much room to work with so I would try to build in more room between the tee and you pump. Then you can use a male/male fitting in the pump, and a quick connect fitting on that.
