I assume the tank is draining into the bilge.
Try closing off the vent hose with a clamp, then check the gasket on the fill and close it. Next I would put air pressure in the empty tank via the drain hose and listen for an air leak. Maybe some recent worker drilled into it or ran a screw into it. Capt. George
