Anyone have a schematic or know where i can find a schematic of the dual-tank setup on a 1977 e250? the po removed the valve and the switch because he didn't know if the back tank worked. I'd need to know where to wire in the crossover switch as a I have a new valve on order.

Thanks in advance

 

nevermind, found a diagram for an '86 f150 with dual tanks since it's basicaly the same thing. Now to hunt down a 5-pole switch -.-
