Manual pumps are generally more reliable but should ideally keep 1 1/2" all the way to and including the thru-hull. Most 12V macerators are a 1" outlet. The line will be full anyway. If the tank is full liquid always levels itself and the drain line is off the bottom of the tank unless you tank uses a dip tube design..
