Review on Gates 31761 Fuel Tank Cap by Paul Williams

I needed a new gas cap and searched the internet for it. This was the cheapest I could find with a lock so I bought it. It fits well, but it only has two areas where it connects to your petrol tank valve, and it's annoying when one of them comes loose and the other is still attached because you have to keep reinserting it until both sides unlock are locked. If it bangs on one side while driving, most likely the check engine light is on!
