This is a 1950's device found on many 1950's Mopar vehicles, it's a Brisko "milage saver fuel pressure regulator" that mounted directly to the fuel inlet side of the carburetor. The device is said to regulate fuel surges into the float bowl, keeping float bowl at a constant level, along with a long list of other "questionable" medicine man benefits ???. This is actually a nostalgic piece for giving your older ride that period correct look- - -easy deal.
