First post on the forum, I've been using it a lot! I'm restoring a 1979 Lionel pop up and I need help identifying a propane hose so I can buy a replacement. It goes from the regulator to trailer. 3/8" NPT on regulator side, similar size flare fitting of some sort on trailer side (goes into copper hard line), 24" length. In this Lionel, all the propane runs is a small cook top. Is this a standard hose? What are they called? Finding the regulator itself and pigtail to the tank was easy . If not standard where do you go to get something like this made? Thanks in advance for the help!
