The UV dye is a very interesting idea! I really think that it’s likely just vapor itself leaking which is why I haven’t seen any drips anywhere, but it’s something to keep in mind. I don’t really feel that it is running rich because the smell seems to come from the engine or tank, but it is also worth investigating. The sniffer tool looks interesting. Never heard of that either. Lots of ideas to ponder!






I have done this with tires before, but could there be some danger in doing this with engine fittings by potentially getting water in the engine?
