Default HELP: Injector O-ring

so i am trying to put my sti injectors in 1.8 rails, but my injectors are missing an o ring and i have had a really hard time finding one.
i have tried most local auto parts stores, plus the Empire CAT store, and nobody has a gas rated o ring that will fit. i went to the dealership but they are pathetic, after an hour of looking up numbers and me telling the guy, "no i have that seal, i need this little one" he still ordered me the wrong seals. (yeah don't go to lamb subaru)
I have the very upper, and very lower rings, but there is one that seats on the inside of the rail...
does anybody know what i should do?
i might try and go to deal with the stealer-ship again. i know they have to make them. i have been searching for a part number but i just cant find one.
i mean what the hell, this shouldn't be this hard.

this is the one i am missing.


i have the uppermost, and the big one that seals on the bottom, but i missing that one little guy, and nobody has a gas rated one!

Are you positive on that number? I got the same number from Jamie @ Subaru Genuine Parts and she said it was a top o-ring and that the bottoms are not available. I've also seen other threads with numbers such as (but not sure which is which):

16698AA050
16698AA060
16698AA080
16698AA100
16698AA110

Any insight? I'm missing the same o-ring for my 07 STI injectors...

Thanks!

yes, for reference, the o ring i got is NOT the right one.
i have no idea what it is. after spending 60+ dollars on freakin o rings i decided to send them to deaschwrks (spelling?) for cleaning, and proper o ring fitment.
