[QUOTE="BigAL07, post: 463231, member: 21619"] Make sure u have the exact fuel cap that your wrangler calls for. Also the exact mopar ESIM module with the green gasket not a black one. Check your purge vapor line from the valve to the intake. If it’s loose at all it will leak. Hose clamp on it will confirm. Also check the white nipple (did I say nipple?) on top of the fuel tank. Aftermarket is definitely not your friend on evap code. I have a collection of gas caps that said they fit but they don’t work. 🍺🍺 [/QUOTE]
