OP has an '03 - does not have a tank mounted electric fuel pump. So, your procedure will not work for him. Your procedure is for later models.
Thanks. You are right.
After reviewing the free downloaded file I discovered that the elephant trunk intake and the fuel delivery system,including the fuel filter, match the components in my van, and they are different in the factory cd which covers the om612/om647 version engine only.
At $19.95 plus $5.95 shipping, for the 2300 page manual I don't think I wasted much money because there are 698 pages, ahead of the actual service and repair section, which include
using the DRBIII, DRBIII error messages, diagnostic information and procedures, component locations, connector pinouts, schematic diagrams, charts and graphs, and 442 pages of fault codes and their indicated procedures.
Thanks for the heads up
Drive Safely
