Fuel [Petrol] Gauges that Fail to WorkAlthough there could be one or more other causes for a fuel/Petrol gauge to fail to work, the answer is YES, a "blown" fuse could cause the gauge to not work.

No The dash with gages will not work due to the engine sensors are different from gages to lights. I have changed 4 of my Chevrolet Celebrities from idiot lights to gages. The gage cluster is a direct fit, the voltage gage will work with no alteration. The temp sensor is readily changeable by purchasing the proper sensor for your car. The fuel gages are the same.
