Nice hand air pump that goes in an instrument panel, has the threaded mounting nut that goes on the back side of the panel ( often missing), original wooden knob, 9" long overall, only fault is that the outlet fitting has been soldered to the cylinder end - does not affect operation and this pump does work perfectly, all threads are perfect and operation is smooth and it pumps strong and positive. $185 domestic postage $12.
Was this pump used to pressurize the fuel tank ?
Yes this air pump is an original that was used to pressurize the gas tank on a Model T era car. On Model Ts, usually speedsters.
