Fuel Level Sensor/Fuel Pump Lock Ring Tool for many BMW models and all Mini Coopers. This specialized tool is used to remove the fuel level and fuel pump locking rings on top of the gas tank. The tool is in perfect condition in original box. Google the part number for more information, or visit www.ecstuning.com/b-bav-auto-tools-parts/tool-fuel-level-sensor-fuel-pump-lock-ring-bavarian-autosport/b8800089~bav. Paid more than $75 for tool with tax and shipping. I'm asking $40.
