Block it up first,then air it out so the bags are down,then dump the tank,then you can pull the air lines.
If you use check valves between the fill / dump valves,you can air up ,leaving the bags full ,then dump the tank & remove lines. I set mine up this way with hard lines going into the bed floor( into bulk head fittings) then into push to connect fitting,so I can pull the bed leaving pumps/tank ,ect. in the bed!!
