My fuel gauge is going crazy.It goes from full to empty and back again,when the tank is full or even half full.The blazer can be sitting perfectly still and on level ground.It doesn't do it as much as when its on an incline,but it is stll eratic.

Hi there ,

this will be either a faulty fuel tank sender unit, or a bad connection at the sender plug, check this out.
