Dual Feul Tanks

[6.5 Detroit Diesel]

Here is a question I hope someone can answer. We just recently got another 1993 Diesel. Exact same as my truck, except the motor is already gone. It has the 34 gallon fuel tank which is in great shape. How ward would it be to set it up with the truck so that I have two tanks? I am running stacks so the exhaust won't be in the way. What else would I need to make this work?

If you don't mind hauling the spare tire around in the bed you can get a tank in back between the frame rails.
