How many orings per injector

Hi all. I want to change all the orings on my m50b25 injectors.
I found on realoem the reference but theres no indication on number to order.
I want to replace them all, the little black fat orings. Are there more orings to replace and again the quantity?
Best regards

I had to do that on mine before i got rid of it. I bought them from an auto part store and then i got the urge to go compare them to the ones at the dealer. The ones from the dealer are significantly harder to squeeze if you try to. They are kind of expensive but they are noticeably higher quality. So i bought those and took the ones from the autopart store back. Just my observations. Good luck. Just go to your local BMW part store at the Dealership.

Hi all. I'll get mine from local agent. Those little are not that expensive and I decided to get all those tiny parts from the local agent.

The reference that I found on RealOem are from those fat ones that are between the fuel rail and the injector. I couldn't find any other references.

The truth is that they are screwed to the head so I believe there's some oring or no oring but that must be together with the injector.

Best regards

Bugsie, i can't quite figure out what you mean by the fat o rings (as opposed to thinner ones presumably) that you're referring to in your post here. To my mind, there is only one O ring per injector. Would you mind posting the part number of the O ring you are referring to, extracted from realoem.com?

Hi all. Of course I can. When I state "fat", visually it's thicker than most orings.

Anyway, the reference: 13641730767

My e39 has two per injector but can't say for sure on the e34.

I can't even get an answer as to where an alternator cable bracket goes after 100 members looked at my thread. You would think someone might help by opening there hood and looking for me. I am in the wrong place. Sorry for the rant fellas but I call it like I see it. I figured out how to put together and install an M60 engine in two weeks. All you need to do is lull an injector out and look. Might take a half an hour tops.

Hi all.

Thanks for all the help, especially 82nd.

Two per injector that was my guess. Thanks again for the help
