Has anyone tryed running an extra fuel tank in the bed with a set of valves to change from the OEM tank to the bed tank?

Next year I plan to change the steel section of my fuel lines. This would be a good time to put some tee's in.

Now there is a suction side and a return? or is there 3 lines?

Do they make a dual valve that with one motion could change the flow on two lines. If you had 2 full tanks, you could overflow one tank buy accidentally running your return into the wrong tank. do they have electric valves also? I don't care if I put a gauge in the extra tank.

What are the details of your truck.

I was just looking at one in the Norhtern Tool & Equipment catalog, listed with their in bed tanks.

I have also been looking into this. For my '96, I should be able to use a pair of Chevy valves, which are electric. One for fuel feed, one for return. I'd wire both up in parallel, so that flipping one switch would operate both valves. I believe Fords also used electric valves. The one thing I need to check on before ordering parts is the size of the fuel lines on the valves, to make sure they are large enough for our trucks.

I would think you would be able to locate a suitable valve in a Grainger catalog; just look for liquid or chemical handling valves. Double check to make sure they are rated to handle fuel/chemicals.

When you wire up the system, you should also be able to wire in a relay to switch between the stock sending unit and the aux. tank sending unit, if the aux. tank has one, to allow the fuel gauge to work. Wired properly, one switch should be able to handle both valves and the sending unit relay, making a smooth switch from one tank to another.
