Im so confused. Where at all the hoses going and coming from to the hard tank and now bag. I’ve got one hose that’s running down the middle of the hard tank and I can’t figure out where it connects. I can take the thru-hull intake to pump, pump to tank, and tank to port side bow bag. I assume it’s the bow bag back to tank, but I can’t find where it connects to the tank. IMG_0609.jpg
