i just finished installing switches and pumps for filling my rear sac's. My concern is that I need a over flow port. My current sac's just have the two holes (fill/drain). I am thinking that the drain pump will let the water by when the sac fill's all the way also letting all the air out. Who out there has had expeience with this situation. Am I going to need to get sacs with 3 port's?
