Why your BMW E90 leaks fuel

[@SyncedCyberSoule]

Was all poly worth it? Or would you have installed solid subframe bushings to pair with the poly diff bushings?

[@soositta4221]

I do not have any experience with solid subframe bushings for comparison, so I can't comment on that. Are the poly subframe and diff bushings worth it from driving standpoint compared to the originals? Absolutely. Be aware that the poly diff bushings will introduce some NVH, and in my case a little bit of diff whine, but I like it, it gives character.

If it’s a breather hose, doesn’t it vent fumes anyway? So wouldn’t it still smell of fuel?

[@soositta4221]

I suppose, the breather system is designed in a way, that it does not smell directly like that. If it leaks, the smell is there constantly.

Do you have part number to hose

[@soositta4221]

The part numbers may vary for different models. Go to bmwfans dot info. Search your VIN number or choose your model, and you should see the P/N under the fuel supply page. P/N for my car is 16126765748.
