When I was filling the tank on our F250 there was some white smoke and diesel bubbling up like the tank was full. It was only about 1/2 full. what could this be?

Using a "fast-fill" type fuel pump will aerate the fuel. It's basically foam and nothing to worry about. I usually slow the fill rate down to allow for more fuel to enter while no foam creeps out the fill port.

Also, winter blend of diesel fuel foams more than summer blend.

I stopped going to the big truck pumps for this very reason. They flow way to much fuel and it will over flow the tank every time. When a trucker needs 200 gallons of fuel he doesn't have time to stand there so those pumps flow way to much fuel.
