I believe that is a pic of the quick release. Do me a favor. Take a look at the pic below and let me know if that is where the part is located.
If you look at pics 2, 3, and 4, they show how the connector is disconnected and then reconnected.
I have to be honest, I have a feeling you will need to purchase a new fuel line and replace it. I don't think that connector can be replaced by itself.
Let me know if this helps or if you have other questions.
See pics below.
