So my old gauge does not work, it was stuck on 3/4 no matter how much fuel in it, so replaced the gauge and same, replaced the cluster with a 90xj full gauges and tach and still shows empty even do the tank is full!, disconnected the sending unit and turned the key and the fuel gauge goes up past full to the max, reconnect and back to empty, already cleaned the c101 connector, checked ground and even tapped on the sending unit to maybe loosen the floater and nothing! Any other ideas? Other than the obvious which is replacing the sending unit that is hard to find ! Any help will be welcome!
