Yes gentle pry with a putty knife. Alternate ends and middle, pry just a skosh each time to keep from bending the emblem.
each emblem has 2 pins, 1 located an inch or so from each end. These press into a friction nut, installed in a bracket in the tank, generally intended to be a one way affair. But go slow and they will come off. The friction nut sometimes comes off with the pins, or it stays in the tank where it belongs. Be sure to account for them for reassembly.
