State of Nevada has mandated temperature compensated fuel pumps, perhaps many others, so that the fuel delivered is accurate at any temperature. If you fuel in Phoenix in the morning it should be somewhat colder by a couple of degrees than the post trip consumption/level. The only practical way to determine useage in the existing system is to have a visual mark or use an instant read thermometer to detect the temperature and fuel level then calculate quantity in the tank. Then there's burping and thermal expansion during the drive.

Could be off as much as a gallon like on my F250
