The ful gauge on my '01 doesn't want to read completly "full" even after I just fill it. One "bar" is missing at the very end. (i.e. not lit) (not the "half bar" at the very end)

When I first got the car it worked fine. (all the bars would be lit) I even tried filling it with more gas after the pump shut off, to the point of it almost overflowing, but it didn't do anything.

It's not a huge deal, but kinda annoying.

 

Ok.
