Here you go; best prices I could find:

I use two of #6747.
They are THREE-tank compatible and cost about the same as the two-tank ones; you can just plug one of the ports or use it to plumb in a drain or something.
I have three tanks.
They do make manual six-ways and eight-ways, but the stem is so long that it soon snaps from the strain of turning both ball-valves.
I had much rather have two seperate valves, plus there are some advantages to being able to direct the return fuel to a tank different from the one you are drawing from.
The place to locate the valves is in the area of the floor between driver and door = out of the way and easily accessible while driving.
I always orient the valves such that the little pointer points forward for FRONT and aft for REAR.
You will also need to incorporate a SPDT switch (or was it a DPDT--I can't remember if it was three or six wires) to switch the gauge-sender signals.
I put this switch in the same area, behind the manual valves, also oriented such that the toggle points fore for FRONT.
I wouldn't let someone swap my manuals for a bulletproof foreverlasting
electric valve and give me a thousand dollars to boot, if part of the deal was that I couldn't ever change back to manual.
