911 SC 7th injector
Supposed that this will be the 7th injector used by the K-Jetronic ingnition for the cold start, I recently cleaned and lubrified the other six with ultrasounds but I'm not able to take apart this one (think it has never been taken apart since 1980).
 Sprayed with K9 with no result. Any purpose? I'm afraid to breack it Somebody knows what is the other small pipeline standing on the rear of injector?

That’s the warm up regulator. Involves cold to warm running. Cold starting is done with a separate injector at the front of the air box.

Lots of info here about the WUR. If the car starts and runs well, it's working as it should. At this point you do not know enough about how it works to mess with it, so leave it alone, or you are likely to cause yourself a problem you don;t have.
