I know my opinion matters very little, but I would never take the "heart" out of a pump. Hey could you still call it a gas pump, with no pump? As far as the old gas in it. what is the big deal? not too hard to run some hot soapy water thru it.No more gas smell. Jack, would you take the guts out of your AIR METERS? You would just have a cute little empty shell.
