    What is this sound???

    I am getting a code for a P455 LARGE EVAP LEAK. I had the car smoked and it was pouring out of the gas cap. I replaced the gas cap with a Motorcraft cap and had it pressure tested and it passed. My mechanic is telling me I need a new filler neck? I have never heard of this. It isn't cracked...
