Maybe blowing it out would be better? Also, maybe it fully drains on its own. I would hope that all Black Tank Flush Connections are the high-point in the system, so I guess you could hook-up a short hose, and drop fluid in the open hose-end with a funnel. Then again .........

Perhaps you need a jar and a funnel?
