The first thought that came to my mind was shutting off the key when filling. Like you said. But that should clear up when you shut it off and restart.
I would however, fill it up and burn through a tank (shouldn't take long ;-) ) a see if it somehow magically disappears.
Could be a number of things! Poor grounds, sending unit screwed up, gauge itself...who knows!? Good thing though...it is under warranty still!
Thanks for asking for me but do realize even though I have Super Powers, I sometimes do not know the answer simply because I have never experienced the problem before.
