Yeah I can hear the noise coming from the passenger side dashboard/glovebox area too. Another member on here just had his fuel line replaced a week ago. His car had a rough idle and the noise came back a couple of days after the replacement. Maybe he will chime in. My dealer doesn’t want to do anything until they figure out what exactly is causing the check valve to fail in the line
