CA18DE fuel rail to injector o-ring part number?

[mbmbmb23]

I'm looking for the part number (OEM or aftermarket) for the top o-ring that seals the injector to the fuel rail. I already have the middle insulator (size of a quarter) and the lower pintle cap insulator (size of a dime). I somehow cannot find this peice on any of the online replacement websites (everythingnissan.com, autopartsonline.com, etc.).

thanks,

16603G - 16636-V5000 Insulator - Injector Per Veh 04 This is the upper o-ring. Fuel rail to injector.

16603F - 16635-V5000 Insulator - Injector Per Veh 04 This is the middle one, which I guess you already have.

This is for the USDM CA18DE, which has a totally different fuel rail from the JDM one. The injector seems to be permanently attached to a small piece of rubber hose. The o-ring might be the same, but not too sure right now... Hope this helps!!!

Thanks for the input. Yeah, I really need an upper o-ring compatible with the CA18DET injector+fuel rail. If anyone else has any thing to add I'd love to hear from ya. I'm thinking that most peices should be the same. I have DSM 450cc blacktops that are going into my DET rail, maybe new OEM DSM o-rings would work? Anyone on here using DSM injectors and have re-used their injector-to-rail o-rings?

thanks guys,
