:( Fuel gauge problem

[dfish28]

Last trip out I noticed the gauge flickering around, then nothing ,totally down on E then it came back to life,but is reading 3/4 tank when I just topped it off at the $3.92 gal fuel dock, and it is definitely full(gas spurts out the vent at that point). Was wondering if anyone had an issue like this before. Will be going to the dock tonight to trouble shoot, hope its a wire, and not the sending unit! As always feedback is much appreciated. One of these days hopefully we will be glitch free...
