Doyou need the one at the top of the injector that fits in the fuel rail, or the ring at the bottom that sits in the manifold? IIRC, there was a vendor that was selling a kit with all new rings for injectors. I'll see if I can find the site. I've changed injectors 3 or 4 times and I only remember there being 2 on each one. The one on the bottom that sits in the manifold is kind of thick and has a habit ofcoming off and getting stuck in there.
