Fat sacs / ports

[loudsubz]

On the 400 lb stockers, is the port size 1" for the fill/drain and 2 ports on the top 3/4" for vent?

Looking to buy a Sumo pump adapter to use my spare 400 and move around the boat.

All three holes have 1 inch threads, the vent fittings are reduced to 3/4 for small hose.

ok I assume this is what I would need to work with the sumo pump
