Air rail o-ring

[Riley]

Does anyone know the o-ring dimensions for the air rail tubes? BMW Part #13417830384

Nope. I’d recommend you just buy a set from bmw. Less risk
also it’s 2 different o rings for top and bottom

Incorrect, the air rail tubes use the same o-ring top and bottom. You must be thinking of the injectors.

Dropping this here for posterity. If anyone needs the fuel line to rail o-ring it's 13-64-1-730-767. I suggest not trying to start the vehicle without this installed 🤣

Realoem lists it as: 7,52X3,53

EDIT: This is for the fuel rail to injector o-ring, not the air-rail o-ring as requested. My mistake.

Can you post a screen of where you see those specs? Genuine question.

I'm glad you asked, because I screwed it up. That supplemental info is for the fuel injector o-rings to fuel rail part number listed above (13-64-1-730-767), rather than the air rail o-rings you requested. There's no supplemental info for the air rail o-ring dimensions on realeom. Sorry about that.
