I guess it has to do with the mesh, but the exact role of diaphragm marked U?
Someone can explain me?
Thanks.

I would guess it acts like an accumalator for the fuel, to even out the gas flow.

I try to build this system (never in my life I've had it in my hands, and I've seen him physically) so I turned to photographs, diagrams and parts list to determine dimensions, features and achieve develop construction drawings for such end.
I turn to their knowledge to query a couple of questions regarding the plunger.
. 1 - what material are constructed glands?
2 -. Equally, which is the material the four packing rings?
. 3 - and cup?
As to external dimensions, I think not having doubts, I usually work on photography or outline drawing, once the scale determined by a dimension known beforehand.
Thank you very much for your help.
