The rubber gasket goes around the filter so you must have a C channel, verify that it is.

The two small 90 degree tubes, I understand, were only included in the 2001 model, later they were removed. My C50 is from 2006 and it doesn't have them either. What I send is the service manual for the VL800 that I have, which goes from 2001 to 2009. The first chapters are the same for all years. It changes in 2005 because they eliminated the carburetor for electronic injection. Check part number 13746-41F00 Gasket
