This is an original Ford-Ferguson 9N tire pump that runs off the engine. This is completely original in the original box from the dealer. This was a neat tool to have if you needed to inflate your tires while out in the field. You removed a spark plug and screwed the adaptor end into the spark plug hole and attached the other end to the tire air valve, started the engine, and let it work to pump up the tire.

This one cannot be used, unfortunately. It is strictly a collectible display case item. The spark plug adaptor end was rusted to where it separated. It can be cleaned up and reattached, but even then, I do not think that it could be used.

I can also, at your option and for free, include extra parts from another engine air tire pump to play with or display. I have both ends, the gauge, and the wrench. The hose on this second unit was so brittle that it would break if you even picked it up.

Asking $75 + $18 Priority Mail shipping with insurance. My email is open above.
