there are o-rings at each end of the injector but if your careful when removing the fuel rail with the injectors you will not need to touch the upper o-rings. and again you do not need to remove pressure reg from rail so you wont need that o-ring either.so if all goes well you only need 4 injector o-rings(they are the same o-ring at each end by the way)


I know the obvious thought is 8 needed (4 bottom/4 top) but my ETK CD shows 5 needed. That's 4 bottom and 1 for the pressure regulator. It doesn't indicate an "o" ring fits at the top. To further complicate things there is two different P/N for the "o" ring pictured (both show quty 5)The numbers are 13.64.1.286.708 (AE?) and 13.64.1.730.767. Can anyone shed some light for me on this, please?? TIA..
