Another Vac-U-Flush Question

My rear Vac-U-Flush pump keeps runinng, presumably not building up enough vacuum to satisify the cut out switch. Going through the trouble-shooting tips I checked all hose clamps and could not hear any hissing sound. The bowl does not leak water through the ball so the next step is to change the duck bill valves (joker valves).
There are 4 of these rubber valves 2 on the inlet and 2 on the outlet side of the pump. Problem is I could only find 2 valves. We're cruising and the supplier only had 2 and I don't want to wait a week here to get the other 2.
So given a choice which side of the pump do I choose or perhaps one on each side??
