That fuel system looks great. On many rally cars they would run the fuel system inside the cabin to prevent them (the lines, pump, filter, and regulator) from getting broken when the underside of the body would rub on the ground or get beat up by gravel. The same would also be true for the braking system. I, however, do not blame you for wanting to put it back to the standard configuration albeit with much better parts. Keep up the good work.
