I CONCEDE ------ TO A POINT ---- BUT IF YOU TAKE A VOLT METER AND TAKE THE GROUND WIRE COMING FROM THE FUEL GAUGE GOING TO THE SENDING UNIT AND MEASURE IT - WHAT ARE YOU GONNA FIND ---- VOLTAGE - AND IT'S LOOKING FOR A GROUND - THE FUEL GAUGE NEEDLE MOVES, HOW MUCH DEPENDS ON HOW MUCH CURRENT FLOWS THRU THE GAUGE LOOKING FOR A GROUND - THE SENDING UNIT IS TECHNICALLY AN VARIABLE RESISTOR - WHAT DOES A VARIABLE RESISTOR DO? IT RESTRICTS CURRENT FLOW ( VOLTAGE) BY RESISTANCE. SO THERE!!!!!
