Commando valve covers ?

If they have glue all the way around that tube, the only way they are coming off is by cutting through the outer vertically in several segments. I'd cut them off above the original and carefully grind 4-6 slices down around the perimeter, only going through the outer one. You won't be able to get close at the base. Going to be a PITA. Maybe some heat first to try and burn the adhesive out.

^^Yup. And overall, BE PATIENT. Don't get excited and rush it. Soak it, heat it, work it around. Cut/grind gently. You'll get it.
Now that I think about it, before you start, I'd be tempted to tape off/seal off the ends of those tubes and pour in some vinegar through the valve cover and let them sit for a couple of days first; then attack them.
