In this video I unbox a New Old Stock MilesMaster 3-in-1 fuel pressure regulator.
This has a fuel pressure regulator, a brass filter screen and a magnet.
This would be installed in-line with the carburetor on a car, MilesMaster claimed it would "increase fuel economy" "reduce wear to the carburetor needle & seat" "prevent vapor lock" "reduce crankcase fuel dilution" and a host of other things.
These were advertised in Popular Mechanics magazine from 1956 through at least 1960.
