Mine was also leaking there too. Had to take it off and re-adjust the clamp to be seated fully on the hose & make sure it stayed tight

That's what I think mine is, sounds under passenger front

Do you run a dv or a splitter valve?

[@carsongrigg1248]

Yes DV

Do you have a CEL for the evap delete and if you don’t how did you get rid of it?

[@carsongrigg1248]

Yes CEL is on due to o2 sensors I believe, I will have to check again if it is the sai delete. If not I am pretty sure a good tune will take care of that. I’m running a mobil 1 tune done near Chicago
