I have a 2002 X10. The fuel gauge hasnt worked since I bought it. It always read full. I installed a brand new sending unit and now the gauge doesn't move at all. The needle flutters around a lil but doesn't go above the E line. I'm assuming the dealer wouldn't have sold me a faulty sending unit (even though I got it online) but I'm not familiar with how these things work together. Maybe I need a new gauge, maybe a bad ground, but I don't know how to find out. All other gauges work fine. Any help would be greatly appreciated.
