That is the SNOWMAN’s logic nothng to do with facts,

The SNOWMAN’s way of not letting facts get in the way of nonsense. 🙃

Looks like you’re right! I didn’t know what ORVR is and how refueling is different on newer vehicles. Come to think of it, that must be why I smell gasoline when I refuel! I read topping of your gas tank can damage the charcoal, so maybe that’s what happened.

Let us know the results when you do the experiment.

The tank vent hose? I believe you – I think it will cause the gas pump to shut off right away. I don’t have ORVR to experiment with.

That can’t happen on today’s vehicles

The ORVR system has an overfill check valve that prevents that from happening,
