Is there a proper name for the connection for the black tank flush connection. Mine is spraying every where on the back side of the fitting. I cant seem to find the same one on the net anywhere . It looks the same as the city water hook up. Iam assuming there is a back check valve in it.

Where is it leaking exactly?

Connect your hose to an: inlet
Near the spray nozzle might be a: back-flow preventor.
In the supply line you may also have a back-flow preventor or anti-siphon valve.
Could be the nozzle fitting itself.
