If you haven’t looked at the carbon canister, pull it out and see if it feels heavy. That’s an indication that the carbon is compromised and potentially blocking the vent flow. I also tried leaving the canister out and fueling up; that confirmed that the canister was the problem. Just be careful as not all fuel vapors are being contained.
