Fuel smell in cabin

[Amy1960]

I have a 2017 GMC Yukon Denali XL 6.2 that has a horrible fuel smell when idling. While I’m driving no smell. If I have the HVAC system on recycle it doesn’t smell only when it’s drawing from outside. Spark plugs have been replaced along with the EVAP canister and solenoid. No check engine lights, runs smoothly, fuel mileage is about normal, no visible fuel leaks. Anyone have this issue? Over it

You may have to do a smoke test
