Been years since I had one of these apart, and I didn't review the info that was posted, but common engineering sense says you need two checks, one at the pump inlet (probably a ball) to prevent discharge from going back out the inlet side, and another on the outlet side, probably a needle, to prevent venturi vacuum from bleeding off the pump jet outlets. Just my thoughts - could be incorrect.
