Lots of posts on just this issue. Most recommend a "Runtz" inline with the gauge to keep it safe at 12 volts. Some gauges can be fixed and some cannot. The gauge is matched with a 30 ohm sender and this is true for both 6 volt and 12 volt gauges. You should check the wire and connections before you pull the dash apart. You might just have a bad wire. Do a search for fuel gauge and you will get a lot of good information. Good luck and have fun. Let us know how you fare.
