see if that black hose isnt hooked into a bigger fitting than it seems... that is right about where the yamaha diagram shows that pump supply hose going... looks like someone hooks up a scrap piece of hose there... that looks like an old piece of fuel return line... you might find that fitting is a regular 3/8" id hose fitting down there...
I think you are right fox...the nipple that can be used for a flush looks blocked off already...whcih is right beside the fitting you have your waterline in from the pump hooked up.
