They must have added an external voltage regulator to the alternator. Other than than with a standard, the ECM doesn't do much other than cycle the grid heaters and run the dash gauges.
The fuel gauge being messed could be PCM related or the level sensor in the tank. They are known for getting worn or getting a loose rivot to make it not operate properly.
