EVER SINCE 50K ON MY TRAILBLAZER, THE FUEL GAUGE WAS BEEN INACCURATE. I WILL LOOK AT THE GAUGE AND IT WILL BE AT 1/2 OF A TANK AND JUST 20 MILES LATER ITS AT 1/4. THEN IT MIGHT GO BACK UP TO 1/2. IT WOULD GO AWAY SOMETIMES AND COME BACK BUT NOW IT IS BACK FOR SURE, AND WILL NOT GO AWAY. I TRIED ANOTHER CLUSTER IN MY TRAILBLAZER JUST TO MAKE SURE IT WAS NOT THE GAUGE ITS SELF. IT MUST BE THE FUEL GAUGE SENSOR IN THE TANK ITS SELF. IT IS GETTING TO BE A PROBLEM. I HAVE RUN OUT OF GAS TWICE NOW. ONCE WHILE ON HILL, IN A VERY EXTREMELY HILLY AREA IN OHIO. THE SECOND TIME WAS ON THE FREEWAY. BOTH TIMES WERE DANGEROUS AS I WAS ON THE MIDDLE LANE OF THE FREE WAY WHEN IT HAPPENED AND, AT THE BOTTOM OF A BLIND HILL THE SECOND TIME. *TR
