Also Jason, the reason I have two separate systems set up for both bow bags is because I want to be able to remove one and keep the other. I don't do a lot of surfing, but when I do I would like to be able to remove that front right bag, set it beside the engine on the port side and fill it up. I was planning on having a valve that I can manually turn off and on on that front right bag so that I can fill just the left and not the right. Then, I was going to have a T-Joint before the stern sac with another manual valve after it so I can close the valve and connect the second hose of the T-Joint to the bag lying on the floor and fill it up. (I would just have that second hose lying beside or on top of the stern sac when not in use).

Does this make sense? Do you think that system will work? I'm just trying to avoid buying a fourth sac and a $100 Tsunami pump to manually fill a sac for surfing.
