DDK - Die Deutschen Klassiker

Hi, Hope someone can help. stripped one of my carbs today and when putting back together i have these two parts left over. I cannot remember where they go. I've looked at a couple of exploded diagrams and can't see them either. Any advice in what they are ? and where do they fit?

I have also looked at the other carb and stripped down and cannot find the parts pictured.

Hi, Found out where they fit. Under the pump injector.
