The tip itself has "6814" on it.
On the body of the injector there is "KDAL 59P6 663" stamped on it. It also has "939" in a circle on it. Of course, it also has "260bar" stamped it but I know what that means.
Near the top of the injector body, just underneath the threads, there is "6818" stamped in it.
It is a 5 hole injector.
Anyone have any idea what injectors these are
