So my pop-up campers propane system stopped working a few weeks back. I could get the interior stove lit, but only a tiny flickering flame. In talking to some of the local hardware stores, they've all pointed me towards a potentially bad propane regulator. The one that's currently on my pop-up is labeled 605H. Do I need to get that exact same one or will any 2-Stage vertical regulator work? Should I also replace the pigtail just so all the connections are new?
