I plan to change the filter in my E320. It looks like my sealing washers (part 62 on the CD-ROM) are black rubber, but the dealers say they are copper. Can anyone explain? Also, the short fuel line after the filter has badly corroded connections and I ordered a replacement. How long do the other rubber fuel lines last?
