Can someone tell me what Gulfstream means when they say a "black flush tank", I assumed it meant that the black tank has a flush system in it, but after looking for the attaching point for the hose for about 15 minutes; with no luck. Unless it is in a weird place (or just hidden very well) on the Supernova's, not any where around the black tank... Or maybe the build sheet lies and it does not have a flush system? Or Gulfstream means something else, Tank design? Any input would be great. Thanks
