This is definitely an interesting one. Sorry you are dealing with it.
It seems that you have verified the AFR data your getting. Any excessive fuel getting into the combustion chambers would show up in this data. (correct?)
This would mean it has to be external of the engine to me. Maybe you could pump smoke into the fuel line at the tank, blocking it off at the engine and verify no leaks? Or pressurize it and do a leak down type of test?
Best of luck figuring this out. I definitely will be looking forward to you fixing it and learning along the way.
Foster.
