Battery Back

Gas gauge on "89 Ford Mustang goes crazy after putting battery back in. What is going on here?

I recently ran my battery nearly dead, and had to take it out of the car to recharge it. Now, after putting the battery back in, my gas gauge reads full if I have any more than a little over 1/4th of a tank. Once I've used enough to drop it down below that, it reads normally. It was working fine before, and the car still runs fine, and I am sure that I installed the battery correctly.

I don't think a battery could have caused that.....you should get your float checked.
