lately my fuel gauge has been a little jumpy . when i fill the tank it marks full then i see it in the morning and it says 3/4 full. and then it'll jump right back to full later on. i dont know if its from the damn vegas heat that could have an effect ?

The gas tank is vented so all that gets released if it gets to be too high of a pressure and it would take a lot of pressure to change the tank 1/4 in volume size.
They are just quirky especially at the top end. They usually run out of the first 1/4 tank than the last so you will be motivated to get to the gas station.Any incline will do it or even starting the car after it sits will take a little time for it too give a smooth reading.
