Well, of course, you can get a replacement gauge, there's places online who specialize in old car parts, do a Google search. Or, just calculate your fuel consumption by the number of miles driven. I imagine your odometer still works fine. So, if you get 15 miles per gallon and drive 150 miles you've used 10 gallons. See, you don't have to run out of gas, wasn't that easy! On such an old car as this, I might just skip fixing it and save the money towards a new vehicle.

If the gauge swings past the fuel mark it is telling you there is a open circuit in the fuel gauge circuit, it could be a broken wire but usually the sender is the problem, check aftermarket, they may make a replacement by now, or have a universal that can be made to work using different resisters in the wiring to correct the ohms to your gauge. You could try a dealer, but that old it is doubtful that they can get it. You could take a chance on a used sender from a wrecking yard if all else fails.

Jtbird, you need a fuel gauge sender, it maybe avaliable aftermarket as a complete fuel pump assembly for around 200 bucks but if your stuck with a dealer part it will be at least double that.

I have a 2002 Buick Century with the same issue. I am not going to pay to get it fixed because I will be getting a different car soon. It's not worth it. What I do is use my credit/debit card and fill my tank completely. That way, I know it is full and I am not running out of gas. I also calculate my trips with the odometer. It was a hassle at first, but I got used to it. You will also start becoming more aware of your usage anyway, so it can be a money saver lol. I never let the gas get low. These 2 things lets me know I'm not running out of gas and I can drive with confidence. Well, I hope this helps.
