If you have a smoke tester you can prob figure out if you actually have a leak somewhere.
Possibly just open your tank to vent right away when to stop to sea level to get it to baseline?

Is that how it works?
The carbon canister and all the evap pumps and equipment are under the car, behind one of the underbody panels, correct? I've never actually been under there before but I'll try that on your suggestion. I have to replace a few suspension components in the next couple of weeks so I will be under there already.
