adding a flush kit?

[CV16]

I have a 2000 5.0 GL PEFS, ser # 4012042852, 3869056. I want to add a flush kit. Just want to make sure this is what I want(link). I have read where some were just for a desalter and not for flushing while running. Also, #24 in the diagram, is that like for all the parts in the upper section? Thanks for any input. http://www.volvopentastore.com/Seaw...on_id.124161212--store_id.366--view_id.787725
