So in the process of installing stabilizers, I nicked the high pressure outdoor gas line with my angle grinder. What's the best way to go about replacing if it indeed has a leak? Haven't tested it yet, will soon.
You can get the copper tubing at the local big box store but you’ll need to find the correct type of tubing. The typical soft copper tubing at Lowe’s or Home Depot is for refrigerator ice makers. It’s thinner wall and the sizing won’t match up.
i plumbed a new trailer that I’m building and finding the right copper and fittings wasn‘t fun. The copper tubing sizing is nominal and all over the place. take some fittings to the hardware store and check sizes.
look for air conditioning and refrigeration tubing. I finally found it at the local Menards.
You know what, I really didnt think about it in a camper application, I have used the flex copper line in houses for gas stoves, fireplaces. It is flexible, so it is soft. My TT has blackpipe for the gas line under the camper. The pop up had the flex copper. If you dont have a cutter/ threader, it would be more of a pain, but probably can be done. And it would be stronger. You can transition to the fittings you need from blackpipe/galvanized pipe.
I just had a leak in one of my copper propane lines that leads to the outside stove. The line had a flare fitting at each end as the upstream end was attached to a T flare fitting.
What I did was to replace that section of line with the proper length of rubber propane hose, premade with a flare fitting on both ends. Worked great and much easier to fish around the curves to the stove quick connect fitting. Was about $15 online for the 10' length I needed.
My end broke on the pop up camer, I reflared the line added a shut off and a new conection, the conection for the high pressure propane was a pain to find and the place didnt want to sell it to me because they said it wasn't designed for it. But it was the original equipment. So, I haven't run the lines, but did work on them.

This was the only place that had the high pressure conection, and I had to call them to make sure it was reverse thread. The high pressure stuff is simmiler to a acetylene tourch with reverse fittings. I went everywhere from a place that had made lines, to a propane place to a welding place.
