Next thing on the list was getting the fuel and air tanks mounted. I decided to mount these on the back half of the frame behind the new c-notch/cross member. I picked up an RCI 20 gallon aluminum fuel cell. This size fit well between the frame rails. I welded in a new 2x4 rear cross member and fabbed up a little ‘cage’ to drop the fuel cell into. Its slightly overbuilt but I didn’t want any speed bumps turning the truck in to the next Exxon Valdez.
