I like the idea of getting one from a ford pickup that had dual tanks. probably wouldnt cost too much from NAPA, or you could try to find one in a junkyard

Electrically switched.

Uses a (DPDT?) switch so that the sender output would be controlled by the one side, and the solenoid power would be by the other side. Connect the gauge wire to the center terminal, and the sender outputs to the outside terminals. Then have the B+ go to the other center terminal and have the solenoid be powered when the gauge for the AUX tank is being read. I am guessing that one from NAPA is on the one tank when powered and then the other tank when not powered. I'd use the AUX tank on the powered side, that way if need be it defaults to the main tank.

Interesting, Ideally you would use another fuel switch. I wonder what they do on trucks for that. I can easy see over filling one tank if not done correctly. It would be a big surprise on day when you pull the gas cap off. I don't know if you can get away with a "T" fitting or not.

That's what I would do. Hook up 2 switches in tandem for the supply and return

On my 70 CJ, I have the stock under seat tank (10 gallons) and a 71-75 tank (15 gallons) in the rear. I took the stock temp gauge out of the cluster & put in a second gas gauge. If you're running the return line, you can get a dual line (6 port) switching valve similar to the 3 port one pictured above. Dont run a tee in the return line-thats how mine's set up & it fills the front tank when I'm running on the rear tank.

I have a dual set up ihn my 71. For you, install a saddle tank from a 55-71 CJ. Run both fuel and return lines to a petcock between the seats. You can use either a manual one from a late 70's Ford or an electrical one from a late 80 truck (both will have a fuel and return line, although the manual one's are rare and hard to find). I believe that a switch from a 87-97 Ford diesel will also work. As for your fuel gauge, if the switch won't flip it in tandem with the tank your using, simply mount a three pole switch next to the speedo head and lable it main and aux. Run the power wire to middle stud, the rear tank to one and the aux to the other(be sure to ground the aux tank sending unit). You will need to remember to switch the tanks both manually or the fuel gauge will not be reading the thank your running.

This is the manual type valve that is in my Scout 800A with dual tanks. Also an option if you dont want to mess with the wiring. The valve handle mounts up through the floor.
