Haha I was just about to post the same thing, I have a similar problem with my 1989 Laredo XJ, all my other gauges work perfectly but the needle on my gas gauge reads past full at all times. and does not move back regardless if the key is on or off.

On my 99 the wiring rotted out right where it come out of the fuel pump.

Alright I'll check that! Thanks for the response... is the fuel pump on the inside or the outside of the tank on the 96!

I Guess let me rephrase that. It rotted out right where is exited the top of the tank where the fuel pump and sender wiring goes into the tank. It's all part of the fuel pump assembly.

I'm interested in whatever answers you get. I just got a 2000 XJ a few weeks ago. When I started it after lunch on Friday the gauge showed empty and the warning light came on, though it had worked before lunch and I had 3/4 tank of gas. I turned the engine off and restarted, and the gauge was working again. It's done that twice since Friday.
