If when you do turn it upside down you see a horizontally mounted cylinder, look for what looks like a ti(y)re fill tube. There _is_ liquid in there, but the cylinder should have about 40psi air pressure in it. It isn't really a pump arrangement. That lever on the side is a rudimentary valve. The air pressure lifts the seat, butt pressure lowers it. The rubber lining of the tubing may also be degraded and clogging the works. New tubing is available.
