Black Tank Flush Hose Connection

[Racerx1699]

Our black tank flush hose connection started leaking yesterday. Does anyone know where I can get this part from? We are traveling a lot right now so I need an online source so I can have it shipped to our location. We are just out of warrantee so I don't think Grand Design would send me one. Has anyone had to change this part yet?

Where is it leaking - front or back side? Often, it's just the O-ring with seal in the input side that needs replacing. If it's not that or a problem with the Pex connection on the back, Amazon has them:
