Asked awhile back but didn't get a good answer.

So my fuel guage on my 07 F150 Lariat will read normal about 75% of the time. Other times it reads nearly full (computer says 350-375 miles until Empty.

I know the tank is currently about 1/2 full and some times when I drive it reads fine, often for a few drives. Then out of no where it will read high for a few drives.

Had it in the shop and they checked and cleaned all the connections. They want about $500 to change out the Fuel Sending Unit (another $300 to replace the fuel pump while the tank is out) but I don't want to just throw parts at this.

Surely someone has seen this.... Just ran fuel cleaner through about 1/2 a tank of gas.... This is driving me crazy!!
