ZL1 knocking
Hey everyone, I have the symptoms of the fuel pulsation noise but dealer thinks the knocking is coming from passenger side header and catalytic, does anyone know the exact part number for that fuel line that has the check valve?

Me and a few others are dealing with the same issue. Does it sound like the video I posted in this thread??

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

I think GM should issue a recall to replace the engine in every ZL1 with LT5's.
