Fuel pump connector leak
Posted: Sun Oct 05, 2025 11:46 pm
The only topic I could find on this is 6 years old. Hoping someone has some new info.
The O ring on the high pressure side of the fuel pump failed last week. I installed an O ring from a set I have. The connection still leaks, but not as much. The O ring I'm using is 6.8mm ID, 10.6mm OD and 1.9mm section.
Does anyone know the specs of the BMW O ring? I can't find anything online about it. I can't find the part number either. A call to the nearest BMW dealer's parts department (105 miles away) indicated that they have no idea what I'm talking about.
