Gas Tank Size

So for anyone reading this I'm just going to sum it up. Smart move is fill up your tank when it is a 1/4 empty, it keeps your fuel pump happy. When your gauge reads empty your tank has 3 gallons left (no matter the size, I know that from experience). The light comes on when you are 3-5 from the gauge reading "E", if you have a digital overhead display like my truck it comes on when the computer estimates you have approximately 40 miles to the gauge reading "E".

I've noticed this. I have a HUGE overhead above full (~60 miles), a moderate overhead below empty (3 gallons, ~36 miles), and a VERY SHORT duration between Full and Empty. It's like 40% of the range is outside the gauge, and 60% between E and F.

Try calibrating the gauge cluster and make sure the gas gauge needle is in the right positions. Hold in the trip odometer pin, turn on the ignition and then release the pin. The needles on all the gauges will cycle up in increments and then settle back to normal. This pic shows you were the different increments should be.

I've had my gas gauge below the red line for E, went to fill it up, still had 3 and a half gallons in the tank... My gas light comes on when I have 8 gallons left, I don't even pay attention to the gauge, Just hit the trip when the light comes on and know I should fill it up before it hits 60 miles (even though it could probably do a 100 miles on that amount don't want to run it too dry).
