I have a been having a check gas cap things come up. I have replaced my gas cap twice and it still comes up. Today I took off the gas cap and looked where the hole is and could see right through . From what I remember I thought there was a silver piece that covers that hole. Do any of you guys know anything about what could be going on here? Thanks.

 

I'd assume that there is gases getting past something somewhere in your evap system... could be a hose honestly it could be nothing ad well. It did it once on mine and has never done it since
