Fuel level sending units

What-- that guy said about the dash gauge::::: Just set your trip od. and fill it when it gets to a 1/4 tank. Now figure your mileage and keep track how far you've gone; and refill accordingly. The gauge will be a way to watch your fuel level when drag racing. Go back and refill to half tank, at least, and fill the tank for the ride home. duh?? racing will get you 2 miles/ gallon, or less for the run.
