Old Edmunds Fuel Regulator

I'm sure this is an adjustable fuel regulator, but I'm not sure if it would have been used with single carbs, dual carbs, injection, for racing, or all of the above. Were there fuel pumps that put out enough pressure that it needed to be regulated when this would have been on the market? What era would this be from, the 50's? It is 1/2" thick, and 3" in diameter. Thanks in advance for any input.

Both ports are on the same side of the diaphram if it has one.

Maybe to smooth out pulses from the fuel pump?

Sure it's not a permanent screen filter? Open that puppy up.

 

Edmunds called that a regulator...not sure what is inside. They made a filter too.
There were a number of highly advertised aftermarket regulators in the early fifties, usually claiming economy benefits.

 

Thanks for the link Bruce. That helped a bunch.

They weren't nicknamed "Flying Saucers" for nuthin. . . Be careful if you take it apart, pieces and springs will be all over your shop. Ask me how I know.

 

Thanks Max. I don't plan on taking it apart...

Anyhow it sure is neat.

 

I have one of those original nifty little flying saucer Edmunds Fuel Pressure Regulators on my blown 59A - it has a screen inside as well as a rubber diaphram backed by a a large steel plate for support .. on top of that diaphram is a spring arrangement whose tension is controlled by the screw you see on the top.
