Mistakenly, obviously, disassembled the fuel pump, thinking that my Selock manual would allow reassembly of small parts, springs etc. There is , however no diagram in this manual, and online I have only found external breakdown. Anyone have a complete diagram or source of the internals diagram?

I am not sure what all you have taken apart, those pumps are pretty simple with not a lot of internal parts. just replace the gaskets. it should be pretty obvious which gasket goes where. I think anyway. maybe post a picture and I can help you get it back together.

The pump is as attached. Inside the body is a diaphram with two sections, with a plastic disk and a spring for each. The two springs are the same diameter and length but one is stronger than the other,( More coils). I assume that the stronger one will go to the large size diaphram, but am unsure
