2005 F200's. The fuel flow (total) on the gauge is reading on average 13.8% off. It says I burn more than I do. This is based off of 9 top offs of the tank (anywhere fo 44gal min to 125max gallons at fill ups) how do you adjust the gauge to read more accurately? Would like to get in within 5% if possible- anyone know hot to calibrate it?
