Anyone have the dash number for the Legacy locking SPRL fuel cap o-ring?   It appears to be 2.5 OD and 2.25 ID but I have one cap that is loose and another that is tight.  Spruce calls it 3mm x 57mm and Wicks calls it 3mm x 56mm both in Viton material.  The dash numbers I reference online for a bag of these appear to be either 2.5mm or 3.5 so I'm not sure of the width or the OD that will best fit.  Thanks.
