Are you saying that the check engine light is on and there is a code in the computer for the evap system?

Do you know the code number by chance?

Was there is gas cap code in the computer? What did the local shop say about the gas cap?

Ok, got it. Thank you for that information.

It sounds like there is an evap leak. This is not a liquid leak, but a fuel vapor leak and that is why you are smelling fuel. This is coming from a component from the evaporative emissions system. Charcoal canister, vent solenoid, purge solenoid or evap hose/line. The fix is to get the evap system smoked checked for leaks to find the component that is leaking and then replace it. That is your best bet as it is hard to find a leaking component without a smoke machine.
