I was driving home the other day and my low fuel light came on but the gauge showed a quarter tank still. I checked my range and it was down to 21 miles so i went and filled up thinking something was funny and i didn't want to run out of fuel. Looked at my gauge after filling and it was way past the full line (about a quarter tank over). So i decided to run a tank through it and see if it straightened itself out. Low fuel light came on at a quarter tank again so i filled up today and still shows overfull. Anyone got any ideas what might be wrong?
