carb leaking how do I fix

My 08 yz450 is leaking gas from the brass fitting where the fuel line enters the carberator. How do I fix this? I see there is a screw right below this spot. Is that to tighten the brass fitting? It feels tight though.

The screw doesn't tighten the fitting, it pins it into the bore.  The screw runs across the bore through a groove in the fitting, which is what allows it to pivot.


The fitting is sealed by 3 O-rings, Yamaha PN 3TJ-14564-40-00.




Thanks. That looks like a easy fix.
