Anyone one know how to fix a gas gage on 94' buick Century?

I have a 94' buick century that I recently got and the gas gauge doesn't seem to be working it sits on half a tank except sometimes when I stop it will completley disappear anyone know how to fix it?Anyone one know how to fix a gas gage on 94' buick Century?probably a bad resistor in the float.....you need to replace the float in the gas tank.......while you're there you might as well change the fuel pump too.......it is a common wear part and is cheaper to replace while you have the tank out any way!!!!Anyone one know how to fix a gas gage on 94' buick Century?you may need to take it and have a shop do a check on it to find out if its the sending unit bad or the gage,from what you have said about it this could be the sending unit sticking on it,and that will have to be replaced,only a shop can tell you at this time what it is then you will know more of what to do on it,either one isn't a real expensive job to do,so don't let them over charge you for repairing this,good luck.
