I just did my maiden trip in my used 07 Cruiser 31QB, and one of the only issues is that the water pump won't pull water from the tank. It will pull in on the winterization tube, so it does prime just fine. I connected to the tank tube and tried to suck in some water myself, and I can neither suck up water nor blow bubbles into the tank. Any ideas what could be wrong here?
