1997 Nissan Altima Fuel gauge not working

When a fuel gauge is not working it is either the sensor in the fuel tank indicating fuel level or the fuel gauge itself. I don't think it is the fuse as all the gauges will not work. That fuse protects all the instrument cluster.
I could be a wiring issue like a disconnected/broken wire. However, it is usually the fuel level sensor in the fuel tank that causes this.
If you knew before your fuel gauge stopped how far you could go on one tank then you could use the trip as a guide to put gas back in. My 4cylinder engine goes about 350 miles before I need to refuel.

To get to the fuel level sensor or gauge, you'll need to remove the rear seat cushion bottom. Next remove the cover over the fuel pump in the fuel tank. Disconnect the electrical connector and cover the fuel pump line with a rag to catch the fuel in lines. (You could disconnect the fuel pump relay in the under hood fuse box and start the engine until it dies. This depletes the fuel pressure inside the lines so fuel will leak out, not spray out.
Disconnected the collar retaining the fuel pump to the fuel tank or bolts whichever style your car has. Remove the fuel pump assembly carefully and take care not to bent the float portion on the fuel pump assembly.
If you have a digital ohm meter can check the resistance value of the fuel gauge sensor. Or you can leave the fuel level sensor electrical connector connected (not the fuel pump connector it will spray fuel everywhere) and put the key in the ignition and turn the key until the instrument cluster lights up. Move the fuel level sensor to full and empty to see if the gauge on the instrument cluster follows. These sensors are not fast to move so allow some time before moving to another fuel level position.

Ohm specifications (test this with the key off)
Full 4-6 ohms
half 32-34
empty 80-83
