returning to dual tanks

[mainermikeyd]

Ok on to my next project for my Big Red, returning her to dual tank status. The truck had only one tank(passenger) when I traded for it, my fuel lines are all still there, but the crossovers aren't there, an no selector valve. Also the cab the truck came from didn't have a dual tank switch in the dash?? The valve my dad found me one from one of his diesel distributors, so I am all set there, the questions I have are has anyone else taken on the same project, wiring up the selector switch, whether any of you have gone to the plastic tanks, and how do I know which fuel pumps to order, 2 outlet, 3 outlet?? I have 4 fuel lines currently on the frame, just need a lead down the right path!!! Any help, suggestions, or personal experiences would be greatly appreciated, THANKS GUYS!!!!
