So when I say running a fuel house from the bottom of aux tank in bed to a t- connector in fuel line, i should have stated the fuel fill tube. You cut the fuel fill tube and splice on the t- connector and let the aux tank trickle into factory tank or only let aux tank flow fuel when you open a gate valve. I thought these little kits were a common thing. I don't want a big bulky pump and filters sticking up. The aux tank will fit under my tonnue cover and all I have to do is unscrew a cap and fill it. My question was , with this trickle method were you keep your factory tank full from the aux tank, how do you change your system to recognise a 100 gallon tank and how would it read an exterior tank. That just doesn't make sense to me, maybe I'm over thinking it but what makes sense to me is that there's no way for the system to read an aux tank and the gauge will show full until aux tank is empty and factory tank starts to drop.
