Can't pass safety inspection - P0447

Did reseat the gas cap, no dice. I'll try a new one and see if that fixes it. Really praying it's not a cracked vacuum line as I'm guessing that could be pricey to replace. Could it also have to do with the evap sensor?

My experience with bad gas caps and trouble codes usually take a couple of cycles before they clear. But that was with different brand cars. Not sure how Nissans work with trouble codes.

I left the filler door open and the gas cap off a Lexus years ago. Took about 2 weeks for the CEL to go away.

It would likely be a rubber evap line that cracked or came loose. Cheap and easy repair typically. I replaced a bunch of them on my 2004 Lexus recently. I just bought the proper size and material tubing and then cut them to fit.

Quick question, what is the "cap o-ring" so that I can apply vaseline to it, also where is the evap line location? Thanks!
