I can't imagine that when you fill, you have to fill until it starts backing up out the top of the fill tube.
And for those that say "just put in X gallons when you get the nth warning", what if your sensor is not working properly? How do you know how much you really have in the tank?
My DIC said I was at 30% for about a day. Then it said it was fine for a few days. Then it said I was at 30% for a couple days. Now it says it's fine again.
So... am I at 30% full or do I have a malfunctioning sensor?
Thanks for any insights.

Just like your fuel tank... pour it in until it gurgles or burps... put the cap back on and rinse any spillage off the surrounding metal and painted surfaces..
