Auxilary Tank HELP

623 3
Looking to add a tank where I can run vegie oil. What I would like is to start my truck on the main tank (diesel) then after it heats up, switch over to the Auxilary tank. My truck is an 04 dually. I think the delivery pump is in the tank. I have found some 6 ported valves where I could switch tanks with a toggle in the truck. Now I need to figure out the delivery pump stuff. Any suggestions.

Maybe check out TransFlo or Zylstra. Zylstra is kinda pricey, but they make a jam up fuel tank....both companys tanks have a withdraw and return line hook up. I have a RDS fuel and tool combo that has the fittings on it, but I put a pump on it.....
