I need to have this cleared up for me....since I am already feeling like a dummy! I am looking into getting 2 150lb bags for the front of my boat....and 1 440lb bag for the back of my boat. Now with this link system can I connect the bags together and just use one pump??????? I am assuming that is it but since alot of you have ALOT more expertise in this area I thought I would ask the question on here! I also figured that I would have to use the UBER pump from them as well..........
