OK, so, with the good info and tips since my last post, where would I buy/ source an O-ring gasket for my brass receiver fitting?
BTW, I went across the Interstate highway to a commercial RV park, and filled my tank easy enough. However, there was direct leakage of liquid propane and hissing straight down from my brass receiver fitting while the guy was filling my tank. He did not open/vent the square nut to relieve pressure as the tank was filling, so, this might be the resultant condition with my weak seal on my tank when filling.
The CW store was certain their orifice was good, since they stated that they filled two more tanks this morning since last night's trying to fill my LP tank.
Just my best shot filling in info on what's going on, on my end.
