Alistair nailed this! Pulled the pump out, turned the switch on and
turned the pump manually a bit. It finally kicked over by itself and
when it did, I dropped it into the tank and ran a few gallons of water
through it. It's running like a dream now!

Oh, it did NOT turn off when the water in the tank got too low, as
advertised in the Bentley. Not sure what that's about, but I think I'm
savvy enough to turn the faucet off when there's no more water coming
out of the faucet and the pump's running . . .

Oh, and the flow coming out of the Shurflo is pretty awesome too!

I love a 10-minute "fix"!
