RICK!!
That is exactly what mine is doing man! It is ******* me off so much! I have taken off the top of the canister multiple times and re set the gasket after cleaning. Torqued the top exactly as it says but still the dam leak off the back at the elbow. It is the fuel supply tube is the line there with the fitting. I ordered it today to replace it and see how it goes. $80 so i will keep you posted.
Also i will attach the pic of where mine is from.
