That's pretty much what I thought. I've found that most pressurized
systems (I'm most familiar with pneumatic ones) work better when there
is a reserve capacity attached to the pump.

I mentioned the cutoff because the plumbing diagram in the owner's
manual indicates that there should be one. It was only relevant because
I thought it might be why the water wasn't working. It turns out that
was because the pump was buggered. The new shurflo works fine. Finally
we have water!

How many GPM does it do? Mine does 5, and was a little more than that
(without the accumulator) from West Marine. Maybe WM is pricey. It is
about a mile from my home, though.
