John,
My assumption is that the pump is in the bay or the tank given you would not want to have to pull liquid too far by vacuum to get to the pump but I really did not do a search for the pump. It cannot be too far away from the tank. That being said, between the two of us, you are tall and thin and I am shorter and heavier so you fit better behind the front cap if the search does lead you there :-)
