Center section yellow plug

[Ty's33]

The center section comes with a yellow plug, I assume it a vent and that I'm to put the metal plug in its place. What is the best way to press in the plug?
Thank you,

Just put a small socket around it so the barb is on the inside of the socket not contacting anything and tap it in....
