I keep reading comments about the accuracy or lack thereof of our fuel gauges with some puzzlement. That only matters of one is trying to live off of the last quarter of the tanks. Before that, no matter how/where you drive you will have fuel independent of which tank is selected.
My experience and recommendation is to do one of two things, both involving ditching the troublesome selector valve. A) put in two Carter 4070 electric pumps with check valves, one on each tank, powered by a quality five pin relay. Wire the normally off side to the rear (main) tank and the on side to the front (aux) tank. Remove and block off the mechanical fuel pump. B) ignore the selector switch. Fill up, drive 250 miles and refill. The way the tanks are ganged together you always have plenty of fuel to go 250 miles drawing from either tank and you really need to stop and stretch anyway.
There is a third option, do both and never look at your fuel gauge unless you like the buzz of wondering if it is accurate or not. Ps, it is not......

How would having 2 fuel gages reading the existing sensors work? From what
I have read there is a lot of confusion about reading the gages and
guessing how much fuel is left. Also, there seems to be a lot of unusable
fuel when going uphill. We may not run out of fuel as often if we only had
the main tank hand had to fuel ever 200 miles.
