adding a bow sac....

I want to add a bow sac to my 02 X-star. Was trying to keep it simple as possible. What do you think of this idea: Put a bow sac in up under the front seats and tie in the overflow line from existing ski locker sac so I can fill and empty both sacs using the same existing pump. Do you think that would work? Would it be too much pressure to expect that pump to fill the locker sac and then overflow into the bow sac to fill it up too? Do you think it would empty OK? The bow sac is higher than the locker sac so gravity would be at work to help out with the empty, but will that make filling slow?

I think this should work, Bob. One issue I can see happening is the pressure pumping water from the locker sack (or tank in my case) to the bow sack might blow the hose off the fittings at either end. Using a hose clamp on a tank shouldn't be a problem. But how could you secure the hose to a screw on sack fitting? Is it secure enough? Or would a hose clamp work in this case too?
Also, positioning the bow sack so the fitting was at the bottom will be necessary for it to drain downhill.
