You remove the pasenger side front wheel, along the inside/underside edge there are 8 or so bolts that secure the plastic wheel well liner in place, remove these bolts and the liner and you will be able to look rearward and see the overflow chamber under the rear end of the passenger side front fender. I think two bolts at the top secure it in place as it sits on a bracket at the bottom. Probably easiest to unbolt, attach the new hose, feed hose back up through opening and resecure in place, then attach hose to top tank. Replace the wheel well liner, bolts and wheel and your done. Good Luck!
