Unrecognized Loose Hose
Hi there.. since two days I started smelling some "fresh" gas smell near the front driver side.. and it's so noticeable only when I'm idling..
I started to play around under the hood.. Then I saw the below hose has been completely disconnected .. I reconnected it back in.. so far so good, I don't smell any fuel smell.
But this hose purpose remains a mystery haha .. so what does it do? and I can see that I can control that green plastic nut (tightening or loosening it)..

While trying to track down a fuel smell that has been going on now for years, the area you have circled connecting to the green cap consists of a number of vapor hoses which over time get brittle. We tried smoking the system but found nothing. I changed every single one of those, including the line going to the PCV valve. Every little hose was hard as a rock, It was difficult disconnecting them because they were practically cemented to the plastic joints in between them. I needed a sharp razor to cut them off. I got all the OEM parts from Lexus and replaced everything. Smell still there, but all my hoses are fresh.

Actually I don't trust mine yet... maybe that disconnected vapor hose wasn't the culprit and smell will come back again .. let's wait and see!

from another previous threads I can see it's usually an issue in the fuel dampers. did you try to replace them? also try to remove the engine plastic cover and set the car idle for like 15 minutes just to ensure that the smell will start to come out...then begin the smelling game... maybe it's one of the injectors O-rings.. I hope.
