Since I installed a new alternator, my gas gauge is much more accurate, it
seems.
Before, it would go from almost full to about 1/3 after just 75 miles, then
sit there till about 150 miles(on the odo after filling up)  At about 200
miles run on a full tank, it would go into the red zone, the reserve..and I
would still be able to drive about 130 miles before I needed to even think
about fuel...
  Now, at about 290 miles driven, I am just at the top of the red...about
where it should be...
  What a pleasant surprise when something you didn't try to fix fixes itself
during a different repair.
