Fuel Pump with no markings but looks to be a #543 or #1539422 pump. Should fit 41-47 Ford 6 Cylinder Cars/Trucks. Please make sure it will fit your application before buying.
NOS or NORS. This has been sitting around for 50+ years. I would highly recommend rebuilding it with modern rubber parts before using. Sold as-is what you see is what you will receive.
