I have found a leak behind hose bib in service bay. I have some pictures of the gray water line going aft
above the batteries to the water service port area and behind the hose bib. my question is how can I get at
it? The leak appears to be right where the gray plastic but joins the brass elbow. (Orange Arrow).
The fill port and the hose bid are in a fiberglass box fitted in with the external power port plus the TV cable
entrance stud. Taking that box off will be challenging.
Any Ideas?

I think all you need to do is take channel lock pliers and unscrew
Finally got the faulty part out. The brass collar (swivel) inside the plastic nut had failed. Not a complicated fix EXCEPT for the location. Nut fastens on a straight pipe behind the hose bib. There is some sort of tee also as bottom of tee is the water fill connection. I had to drill a hole in fiberglass housing above hose bib to put a fiber optic camera in to see things. It was necessary to lay on batteries to reach it and lost a little skin and suffered from back contortions but got it off.
I will rest a day or two before I reassemble it.

Repaired. Lots of time to fix a $7.00 part. I hope no one has to fix this but if you do this is the part. Plus a couple of 1/2" Copper Rings.

Be sure to completely dry out anything that got wet (particularly the basement floor/beams/sandwich).
Fortunately for me I saw this leak right away when filling fresh water tank. So water was cutoff immediately. It drained straight down the outside of water hose through the sewer pipe manhole. No significant leakage noted. I hope.
