Today, after I filled up the tank, my fuel gauge only went up to the 1/4 tank mark. It did go down from there rather rapidly to the point that my low fuel light came on. I know the tank is full. (I double checked by filling again when I got into town. It only took a couple of gallons.) Where are the electrical connections located from the sensor unit to the gauge so that I can check those for loose connections? I'm guessing that is what is going on. Also, let me know if you think it could be something else. Thank you.
