Curious if you all have noticed a drop in mpg since this started?

Has Toyota completed a "smoke machine" test? Usually that's what I would do when I'd have a vehicle come in with an issue that was fuel and evap related that was harder to visibly see.
OP - Wondering if the dealer did the UV test as 127.0.0.1 suggested. If they didn’t, ask them why not.
Also wondering the same regarding the “smoke test”.
I feel like dealerships aren’t as committed to finding a solution as the owner is. They run one test (EVAP) and when the results show no problem they assume there is nothing wrong? Which would make me wonder if they smelled the gasoline when they had your 4Runner in the shop!
Take it back to them (or another dealership) and suggest that they run the above 2 tests. Seems like they need some prodding.

Yeah, I think this is a major concern! I have not noticed a problem, but my vehicle is outside all the time (garage is my workshop). I have not smelled it whie driving. I see you are in Denver...is it cold outside (yeah, I know) but much warmer in the garage? It is possible that, with enough temperature differential, that the fuel in the tank would warm up and expand enough to let a bit vent out of the pressure relief. But that should not happen while driving--at least you would not smell it inside the cabin. Just a thought, but as others have said do not let the dealer pass this off. As you know this can be a safety and health issue.

Not that I've noticed but this thing doesn't get great gas mileage anyway so hard to tell.

Interesting hypothesis on the warmer garage and things expanding. I would buy that if it was a long time before I smelled the smell but give it an hour after I get home and it's pretty bad. Not to mention smelling it while driving makes me think something else is going on.

Yes I agree.. I don't know if they did the UV test as I don't recall them stating that and don't see it on the paperwork right now I'm waiting for Toyota corporate to get back to me to give me next steps.

I'm not even sure what a smoke machine test is but they did not mention anything about conducting one of those
Did you find out if the techs at the dealership were able to smell any gasoline odor? If they did, and they returned it to you with nothing else but the negative test result (on VAC test) done, then I would DEFINITELY NOT return to them for any further help.
Hopefully Toyota corporate can give you some constructive direction toward a solution.
