They are in the injectors themselves and also in the aluminum blocks that are mounted to the back of the engine. Do a Google search. The info is out there. I bought the kit on ebay to replace them all.
You should ask in the motors section.

The hidden filters are in the high pressure pump
Lots of videos showing how to change them out

If you go to the Yamaha forum on BBC, you'll find maintenance tips pinned to the top. I believe this was one of them. If not do a search on BBC, there is plenty of discussion about this. Hope this helps.
