dickandlois Report post Posted February 3, 2012 I got to ask what kind of coach,and what kind of propane tank. I have made up an adapter to fit my system that allows me to connect one of my small Argon / CO2 tanks to the propane feeder line, to test for leaks when the system needs testing with no propane.
