Fuel rail shraeder valve - uh, where did this washer come from?

Is this from the shraeder valve or the adapter on my fuel pressure tester?

If the shraeder valve, which side did it come from?

What is WHAT? the little piece of rubber?

That piece of rubberlooks like it is either from your test adapter or out of the inside of the screw on dust cover for the test port fitting

I said in the title - the washer, so yes the little piece of rubber, thanks. It doesn't seem to fit in the dust cover, so OK maybe just from the tester adapter.
