1998 TJ wrangler - fuel pump sending unit / fuel gauge

I just bought my 98 tj and i have a problem. I filled up the tank one day on the way home. The next day i went on a 5 mile loop to turn in some job applications. When i stopped at the first place it said i had over 3/4 of a tank(wow that seems low). When i stopped at the second place, it said i had less than 1/4 a tank (what?!). and when i was leaving the third place it said i had between 1/4 and 1/2 tank (...). What is causing this? could it be the fuel pump sending unit, or the fuel gauge, or somthing in between? Is the sending unit a recalled item?

thanks,
chuck

I had my sender replaced under recall. The gauge appeared to work normally but would still indicate a round a 1/4 tank when it was actually empty.

It might be that it's a problem with the connectors at the back of the cluster. Next time it does it try giving the top of the cluster a whack and see if it moves. There are a few threads about cleaning the cluster connectors if you search.

Also try pressing the odometer reset button, turning on the ignition then releasing the button. That will put the cluster into a test mode and all of the gauges will swing back and forth. The small gauges should run in sync. If the fuel gauge doesn't move like the others you might have a screw loose on the back of the cluster.

well the gauges all work acorrding to the diagnostic. i cleaned the electrical conection at the tank, and it is still funnky. the sending unit is not a recalled item for my 98. the parts are lookin at around $330 to fix. I guess this means i will be using paper, my mileage, and my mpg as a fuel guage for now. Thanks guys
