Thank you all for your help. I have to talk to the service manager at the repair shop where the Monaco is waiting, to get the info on the part.
It is a "quick connect" or "push to connect" not a screw on part. We have taken a 1/2" off the line and tried to "re-connect" it to the valve on the back of the dash, and that did not work, either.
I've been to Napa, Pirtek, Camping World, and the new Monaco owners Allied Recreation Group, to no avail. I will try NWRVSupply.com and a few others tomorrow.
If you think of anything else . . . I'll be watching for the help!
