1957 Cadillac - no idea

[The1957Mechanic]

This is another leftover part from a build that I cannot identify. It was given back to us from the mechanic after finished a 1957 Cadillac. 

Any ideas what this is? a clutch maybe? It seems like something meant for the trash rather than spending the time to sell it.

Let me know, any and all help is appreciated.

It's a used fuel pump. Could be for a caddy.  Style looks about right.

Thank you!

A guess would be it's for a 1960-1961 Ford, Edsel or Mercury V8. Post the number on the flange by the long arm at the top of the picture to verify.

Will do that tonight when I have the part handy

Fuel pump with a combined vacuum pump on the bottom, probably to power windshield wipers.

It looks similar to the pump on my 1957 T bird, with the two vacuum lines on top.

Also called a "Dual-Action", or Dual-Diaphram" fuel pump.

One pumped fuel to the carb, while the other created vacuum to operate wipers, etc.
