I picked up a stethoscope and tested everything. It does sound like it’s coming from the fuel line. I messaged a another ZL1 owner with the same issue and he said his dealer replaced the fuel line. The car was good for a bit but then the noise returned. My guess is the new fuel line was defective or the issue is somewhere else. My dealer is going to check it out next week.
