They were all outside back in the day. It will age with time, as with anything. It will eventually turn gray or brownish. If your restoring your pump as a patina pump (unrestored look) I would want it to be dirty. You can buy ones that are already stained slightly brown, then you gotta rub them in some dirt, gas and grease. If your pump is restored nicely, just buy the bright white one and they will age gracefully together.
