here is a pic or two of my set up, I cut out the spare tire holder & welded in a 1" x 1" square tube frame, it is a Jaz 16 gal Pro street Fuel cell w/ sump from jegs it'll run you @ $190...and about $40 for the tubing, then time to weld it in...that's just how I did it, some of the guys mount it in the bed, some under, some run the plastic cells like mine, some run the aluminum ones....
