Rule pumps for Fat Sack

I have DD boat and would like to install a Simi auto system for 2 fat sacks, one on either side of the motor box. I would like to use 4 Rule aerator pumps as I can get a discount. My Fat Sacks are two yeas old and have 3 waterbed fittings.

I would like to install the empty pumps directly to the fitting at the bottom of the side (back) panel. I will use one of the top fittings for empty and the other for vent.

I would like to T into the intake hose and install the fill pumps directly to the raw water pump.

Does anyone know which module would be best to use in either application? I am thinking the 700’s would be enough. Through hull for the sacks and threaded (npt) for the fill? Will two 700’s (or 1100’s) be too much for the raw water intake?
