Review on Stant 10811 Fuel Cap by Stephen Cooper

We do smog checks here every two years and the fuel cap check is part of the old car check. The rubber seal lasts 2 years. So I end up buying one every 2 years because of a dry cracked rubber seal. Maybe the ethanol mix destroys them? I think the Stant is at least as good as any of them, but be prepared to replace it in a few years.
