What size is this banjo bolt?

Ive had it with E28Goodies, his is maybe the 3rd order they severely messed up. Missing the banjo bolt, waiting 9 weeks now for a replacement, car is on hoist the entire f-ing time and they simply refuse to/avoid telling me the dimensions so I can order elsewhere. I don't even want the replacement from them, I just want to use the stupid hose I bought from them in this conversion.


Can anyone with a good eye tell me if this bolt is used elsewhere or what the spec is? I will just buy 3 or 4 and try them all.

I'll try to help here, but you didn't give the exact info and it may or may not all be the same.

Looking at Realoem, it appears the high pressure side is 14X 1.5 X26 The length assumes the banjo length is the same as factory. Suction side appears to be 16MM, but it doesn't note thread pitch. Measure it to be sure, the difference between 14 and 16 would be clear I would think. Check on Realoem for your exact model, I put in a US spec 535i.

Low pressure is the same thread pitch as the high pressure, just a larger diameter = M16 x 1.5.

Hmm.. so to update.. the bolt sizes (at least on my car) here are wrong. Its M16 and M18 (both 1.5mm pitch).
