under bed auxiliary fuel tank
I have a 2014 Ram 3500 CC 2x4, Aisen w/4:10's and I would like to add an auxiliary fuel tank but want an under bed mount unit. I also was wondering if there would need to be any changes to the def sys...

I have a short box 4x4 and switched out the factory tank to a 50 gal Transferflow one. Like AP said, get fuel as low as possible in stock tank, disconnect everything per instructions, install new tank per instructions. Given everything that's under the truck, don't see where there is room for a 2nd fuel tank--just replace stock tank w/ aftermarket (Transferflow or Titan). T-flow tanks are made of metal and Titans are plastic. Titan probly easier to handle.
As for dealer issues or codes,w/ aftermarket tank, NO. T-flow gives you a new float for sending unit so gauge reads right, but the distance to empty will not work.Have noticed the trucks computer for fuel used/mpgs is spot on w/ the T-flow tank (same as w/ stock one).
