I put on some rear quarter-panel armor last night and now I have an "evap leak (large)" according to my code reader. Does anyone have any idea what I must have drilled into? 2006 Sport, btw.
A friend with a JK had some work done in a rear fender well. Next time they went to fill up gas there was a huge leak in the fuel filler hose spilling gas on the ground. The installers hit it with their drill.
Thanks, everyone. From where I was drilling, I'm fairly certain it's the fuel vapor canister. I can probably rent a smoke machine from Autozone or O'Reilly's to confirm. I'll try to remember to update this thread once I'm done with the whole thing, in case it helps anyone else in the future.
