The EVAP manual does say to mix and match seals as needed. Personally I feel that's kinda stupid cause some it causes confusion and we should all be testing the same way. If they said, Jeep= remove seal X and put seal Y, it would make sense.
tested an 87 c10 pickup yesterday that had those little fang looking things on the gas cap. An evap adapter did not fit so I entered n/a on evap test but have a feeling that'll show up on the monthly report card.
