How are you cleaning - circulation pump or pressure pots? If this is the Shurflo Beer Ace II and it does not have a bypass, is there some other type of optional equipment on the pump you have not encountered before? Or is it just the pump?
As for the series, you will require a cleaning cup on the feeder keg couplers and depending on if you are circulating or pot cleaning, either join gas couplers with double flusher or place coupler on pot.
