Fuel System Part, Level Sender Adapter

[eskirvin]

Fellow Members,

I can't seem to find a part on any diagrams, but it is present in my 2005 X5 4.4. There's a collar, made of plastic, called the "Fuel Tank Level Sensor Adapter Ring" on the E60, that I can't find on RealOEM or any parts page. This is perched on the fuel tank and it is what the metal screw cap actually screws to that hold the level sensor in. It effectively clamps the sender to the tank.

Any ideas where I can buy this part? The part looks like the following part number : 16146750466
