I went to
Yanmar last week and they changed the filter
references once again! They seem to do this on a nearly yearly basis.
I think you would get more interest if you gave some more information about the filters. What
engine you planned to use them on, what are centrel screw diam and length, what O ring diameter. After all they are just filters and will fit a whole lot of Yanmar (and other) engines.
Edit: I just checked, they are the correct
references for my 2004 3JH4E.
