--------------- END SUPPLEMENT ---------------

An improved 7W9787 Service Procedure Film (same part number, but formerly it was a plate) is used to identify filter selector valve locations for the duplex fuel filter. The former plate shows valve locations for right hand service fuel filters ONLY. The new film is for both right hand and left hand service fuel filters. The new film can be mounted directly over the former plate for engines with left hand service or a 4P0447 Service Plate can be ordered. The new service plate is made for the new film.
