Fuel Injectors seals and rings

I pulled the injectors on my 2003 A6 4.2 to do a cleaning. The problem is I can only find replacement rubber o-rings for these and not the plastic ring that goes on the tip of the injector.

Are these available anywhere? Its hard to replace the front o-ring without removing the plastic ring and the plastic rings are so stuck on there that they often break when pulling them off.

So far, the only option I have found is replacing the entire injector. Any suggestions on a source?

Thanks,

Check out http://www.autohausaz.com. Replacement injectors are about $72 a pop. They also sell the seal ring kits. Once you have the injector out you could try some solvent, alcohol, PB Blaster, or similar to see if it loosens the ring. Could also try setting the tip (only the tip)of the injector in some very hot water for a couple of minutes. It might swell the ring enough to let you slip it off.
