The fuel gauge is on what is called a float. The float rises and lowers according to the level of fuel in the tank. That reading will change. If you are going up hill it may look more full than it really is, or if you are going down hill it may look lower than it really is (that could be the other way around.) The float moves freely and it will rise and lower. When you fill up and are on level ground it should give you a close to accurate reading.

The sending unit in the fuel tank is probably bad.
The voltage gauge on the Blazer is not the most accurate (cheap) When using the signals the voltage draw on the system is enough to make the gauge move slightly.
