ya know there's one other thing you mite be intrested in.
I ran a secand tank in the bed for a while. used a valve inline to switch it.
well I would switch over to it and the fuel return would send the rest back to the main tank, so as I would drive down the road my fuel would go down and when I turned on the valve and run the motor from the tank in the bed
the main tank would refill.
took some time, like 30-45mins butt not nearly as much work as the tank swap I did latter.
just have to be willing to lose a bit of bed space. if it had not been for the cab-over camper I
take hunting I never would have done the tank swap.
