Andrew,
I found the parts, but not all.
I DO have spare filters but I do NOT have the connection part to engine cover because when I replied earlier I did not realize I used it on my model. That is my fault, I am sorry for that.
Anyways, if the filters (and respective pipes) can help count on them. Just drop me a line with your mailing addres to the email at the header of this post.
Maybe someone else here can provide you the missing part I mention.
HTH
