I've searched the archives and find the fuel filter is located in front of the rear driver's side wheel. I'm somewhat confused on how to access it. Do I have to access it behind the rear seat and access hole, or can it be reached by removing the inner fender well? Also, how would I know (visually) if the fuel filter has been updated to the newer version?
