What is this copper compression ring for

[R32D2]

This ring, smaller diameter than the copper oil and water rings was in the gasket set for the RB26.Can anyone tell me where it belongs.It appears to be a compression or collapsable ring. Also where does the gasket go? I have not taken apart the fuel rail, as there was no fuel injector O rings to replace the originals.Thanks for the help.How do I attach a pic of the parts? I can forward to you by email if needed.

If you are looking for O rings and injector seals, they are the same out of the 89 240sx Ka engine. I ordered the deals and rings for 6 of the Ka injectors, and they all were a perfect fit for my rb26 injectors.

Thanks for the info. I posted a few pics on my Facebook page. Can you identify the copper washer on left. Thanks

Its a oil drain plug washer on the left. Use with the flat end against the pan.

Thanks for the help.Assembled the rotating assembly yesterday. Oil pan is on, so when I hoist it up, I will try it on the drain plug.
