Yep, it amazes me at how they can design systems with traction and braking control at each individual wheel, but a linear reading fuel level system is that hard. Maybe just unimportant to sales.
as a side note; I had this F350 dually with factory twin 17 gallon tanks... at 5mpg towing, I was pulling into a filling station every 150 miles.
You could watch the needle move, I swear
