Fuel Pump Lock Ring Tool
It looks like the $150 version that's verified to work is similar to cheaper offerings on Amazon.

"Alternative":
This one even says it's compatible for "W204" vehicles, and since ours is X204, I feel like the C class shares the same lock ring?
Anyones feedback or experience with this would be greatly appreciated.
