The main gas line runs through the front cross frame along the right side rocker panel up into the lower part of the rear well exiting about the center of the well to a cross member and over to the gas tank.
The brake line for the rear goes thro the same cross member but on the left side. It follows the the rocker panel to the rear well area and cuts back to the rear axle where it connects to the splitter and then goes to the rear brakes right and left.
The emerg also goes thro the center cross member towards the left side. It connects to a cable there which is connected to tightener then splits and goes to the rear brakes.
Sorry I don't have any pictures.
