Use a very blunt screw driver, or very instrument as you dont want to break the screw rim. I have to say when I removed the pump/sender unit on our estate i did not spot the alignment arrow/mark.
If fitted incorrectly the float can float can foul the tank wall, and even sit on the shelf inside the tank giving a false reading.
If the float was sticking some taps on the top of the tank would free it i would have thought.
How long has it been doing it, just after you brimmed the tank ?
Has the pump/sender unit been out of the tank before ?
