...so I was pumping gas and the pump never clicked off when the tank was full and gas came spilling out of the nozzle and all over the ground. Never happened before so I blame the pump. Should I expect the check engine light to go off sometime down the road because my carbon canister potentially has excessive contamination from having absorbed some of the excess gasoline?

 

No....You are good!

I have never gone to the gas station and not topped off to the brim
