What is the hex key next to gas cap

[HFarr]

Anyone know what the hex key is to the right of the fill cap in this photo? It's on a 2021 Makai. I have fill caps on both port and starboard sides of the boat, but this hex key is only on the starboard side. Just curious.https://uploads.tapatalk-cdn.com/20210725/d7b84d3654b468a79d9de1489bd52007.jpg

It’s to vent the gas tank.

Yep. Just noticed this weekend if you put your hand up to it as you are filling up you can feel the air venting out.

Makes sense, and I thought that at first, but didn't see one on the other side. I guess it can still vent both. Didn't really look too hard to figure it out.
