CruisingOnTheSound 0 Report post Posted March 20, 2021 M.O.S.T. I need to replace the bilge pump. I got in and it looks like there are 2 pumps in the engine bay, pump- float sw- pump I had not seen the second pump until recently. I was planning on installing an Attwood SAHARA 1100 and removing the float sw. Could you explain how the existing system works does the float sw work on both pumps?
