Started out as the "check fuel cap" but soon progressed to a true MIL showing a code for evaporation leak. Tried "funnel banging" the filler dry, with compressed air and with silicone spray. Reset trouble light but it came back. Multiple attempts.

at this point I need to narrow down where the leak is so I can fix it. Likelyhood it's the fuel fill? Suggestions?

 

Smoke test it.

 

Seems to be the only option. $90-$100 at the local Ford dealers. Trying to find some DIY options, liking a cheap halloween fog machine, but nobody has them in stock somehow.

 

There will probably be plenty of used ones available next Wednesday.
