Not much other than fit could go wrong. I have to trust that the venting works, as I don't have any simple test. I only wish it had been all that I needed to fix the check-engine light diagnostic code. I'm still trying to isolate the culprit for that issue, but at least I have eliminated the possibility the gas cap was at fault.
