Doing that fills your evap system with fuel. I fix about 2 cars a week for the owners overfilling the tanks. It fills the evap charcoal canister with fuel and burns up the evap vent solenoid. Costs about $500 bux to fix at the dealership........ Just saying... stop filling when the pump clicks off. Your s10s system may prevent it from doing this but almost everything GM makes if you overfill regularly it will mess it up, trailblazers, envoys, 99-up trucks. etc...
