Ah, good to know. That lines up with the symptom!

Maybe try to remember when you last fueled up, then after that look at your credit card statement and see if it lines up with when you think it was . . . ?

. . . then maybe drive 50 miles on a highway or freeway, then go to a gas station and see if you end up putting about two gallons in?

the ORVR is resposible for shutting off the fuel nozzle. The canister is ruined by you shooting air through it, and its strange it had a lot of liquid fuel in it.
The purge valve is probably damaged by your pressure to. unless you regulated your air line to small amount you probably ruined all 3 things
