Intake water Karcher

[Kiwidomi]

Hi everybody,
I'm new on this forum. I'm 68, located in New Zealand, and use to do everything by myself when possible.
I got some issue with my Karcher K3.170
I have dissassembled the water intake and get now some parts I don't know how to re assembly???
Not sure too that all parts come from the Karcher.
You'll see on the photo the parts I get. Can somedody tell me how,to assembly them and if some of them don't belong to my Karcher.
Thanks in advance.

Thank you TimboTwo,
I had a look but they don't find my part no.
And also I think that I will not find this part disassembled. I am hoping someone will have do it.
