you can change any of the bulbs, including the low fuel bulb, via the left speaker panel, just take it out and set to the center of the dash. it's instructional to then get out of the car and look through the windshield into the speaker opening, you can see the back side of the instrument cluster, the printed circuit membrane, and the bulb holders. The two larger ones that are a bit towards the top are the two that illuminate the instruments for night driving, the others are all in a row with the battery/charge one being a different color holder.
The sender for fuel is a two piece affair (it's different in later models, about 1990, did the original poster say a year if so I missed it sorry) and has a float, two thin copper wires that it does some resistance magic through and the gauge reflects the level of the float via that changing resistance and shows it as a level at the gauge, and that third wire in the connector goes to a wire that attaches to the stop at the bottom of the floats travel, the underside of the float has a shorting connection across it and when the float bottoms out that completes the signal to cause that little orange light to come on.
So... if you are handy with a soldering iron...
you can take the sender out, PLEASE do this OUTSIDE and be prepared with some rags or plastic bags to keep it clean, it's a 7/32 nut driver to take the nut off the blue plastic bottom of the sender. the silver tube slides off. you may see broken wire or wires inside it. If the low fuel gauge is coming on look for the single wire from inside the top cover to the bottom being loose or broken. if it's broken in the middle and not at the tab on the bottom... you could snip it close to the top to disable the orange light. If the tab where the wire mounts on the bottom is broken, foresips (sp?) fine solder iron and solder and a steady hand and you can reattach it. if the fuel sender has seemed intermitant, use brake cleaner on the wiper contacts in the float, when you seen them it will be apparent that they need to be cleaned. DO NOT push, stretch, bend or otherwise screw with the wires on the float path. you will break it.
cheers!
