The service manual calls for a fuel filter replacement for the 20,000 mile service. I went to my dealer the other day to pick one up and he informed me that although the manual might call for it I really don't need to replace it. He said the fuel filters are much more durable than they used to be and it will go much more than 20,000. Anybody agree with the dealer or should I just go ahead and replace anyway? The bike is an '02 Superglide and the filter is original. My opinion is even if it's only 20,000 miles that filter has been in there for 9 years and probably needs to be inspected/replaced. What do you guys think?
