Electrical help?

Hi everyone, I have a 2013 C300 4

Still old electrical pump attached trying to disconnect from the electrical hardness please help
Matic sports sedan and the issue now is I'm trying to replace my fuel pump because it's giving me a low pressure error code on my diagnostic tool. And I'm replacing it after replacing the fuel pumps that are placed under the seat in the back I already did the steps that is required from the Mercedes-Benz worksheet. But I just can't remove the electrical connection. My engine type is a M276. I already attached a photo on here of the electrical connect. Please let me know if I need to push in on the tab to release it or what method should I be using to release the electrical harness which is called the quantity control valve
