I’ve been getting the gas cap code off and on for years now. I can wash the gasket off and it goes away for a few months, but then it returns. The cap itself is in showroom condition. It’s just the rubber gasket/ring that appears to be “segmented” all the way around.
Has anyone ever replaced just the gasket on the gas cap for this vehicle? I know I can buy a whole new AC Delco gas cap from Rock Auto for $20, but to me that’s wasteful. Looking at the cap, I really can’t see how it comes apart, though. No visible screws, but it must separate somehow … or would you just use a pick and pull the gasket up and off that way?
