I have a small propane heater, Mr Buddy, or something like that. I takes a 1lb propane bottle.
I have made a long hose to connect it to my 5gal tank which is outside.
After only a few months the thing stopped working, pilot would not light. I disconnected the gas line and then removed the regulator. When I disconnected the low pressure side of the regulator a reddish light grade oil came out. Lots of it.
Any idea what is happening and why?
