Dual gas tanks on a 71 f100 4x4

[mrmtbaldy]

I am having trouble determining if this is possible. I put a bed on my truck that was originally on a 2 wheel drive f100. It has the auxillary fuel tank setup just behind the cab in the side of the bed. My question is, my truck's transfer case is in the way of the auxillary fuel tank. Is there a tank setup that will work for my truck?

not that anyone has figured out yet. the only thing soem of the 2wd guys are doing is using a mustang tank. or the 73-79 aux camper tanks. but those are very hard to come by.
