I've been driving around now for well over a year with a fuel gauge that reads full when filled, but once it gets past 1/2 way, the needle goes the opposite direction towards the full position. I use my trip odometer to determine when I need to fill up (roughly around 290 miles city). I know that this is probably the sending unit, however, I also know there are some tech notes out there that say it'* a resistor problem.

The 00'* have a nice trap door in the trunk, which makes removing the sending unit easier than dropping the tank (such as the case w/ my 99').
Does anyone have any suggestions for the 99' ??
