Ok, I watched the video. I have always filled every vehicle up until it drips out the top. The only vehicle that didn't like this was one of my motorcycles. It stuttered until I had burned off some of the excess fuel and it ran just fine. The other vehicles never gave me any fuel smells ever. Maybe the gasoline never made it to the canister. I understand what he is describing but none of what he was saying ever happened to my vehicles. The only time I had any kind of gasoline odor was when it would do a little more than drip out the top and get on my shoes. Then when I got back in the car there would obviously be a gasoline odor in the car.
With my new truck I have not taken it all the way to the top. I'll put another gallon or so in after the pump clicks and so far I have not had any issues.
