    FUEL CAP FOR 2019???

    Any with the new 2019 models get a aftermarket fuel cap yet?

    The one for the 18 I had laying around doesn't work due to the ribs they added in the green plastic.

    2021 2500 68RFE..... I'll just keep the goodies a secret!!!

    Same. The carli cap fits perfectly.

    EDIT: I'll mention that this is the same fuel cap that Carli has sold since I had my 4th gen in 2015.

    The one I have from my 4th gen can fit but the o-ring is not sealing due to those ribs.

    That’s weird. Well the Carli one is cross platform and cross year. It will fit any diesel filler neck without a discriminator. Plus it’s anodized aluminum and has a magnet to stick it to the door while you’re fueling

    So the Carli one seals up on the face(flat surface) and not down inside the little green neck since into no longer a smooth circular tube anymore because of the ribs now in the tube.

    Hows does the round o-ring seal that?

    The top of the cap is flared to butt up to the top of the filler neck. The o ring is there to provide a tight fitment to hold the cap in place, not seal off the neck. The top of the cap is what’s there to keep dirt out.
