Ok, so for quite a while now I've been getting a gasoline odor coming from around the drivers rear wheel well. I have also been intermittently throwing p1441 codes. I started by having the fuel filler tube recall done at the stealership, hoping it was in fact rotted and emitting vapor. The issue continued as did the intermittent code, so I replaced the vacuum cut valve, bypass solenoid, vapor canister and purge valve, still getting the odor. It occurs while the truck is running at temperature and right after shut down. I'm lost, am I missing something? Trying to avoid having to drop the tank to see if anything is loose or disconnected. Any thoughts or suggestions are greatly appreciated.
