no i dont but if you want to use an old reg.make sure you check it to make sure it works.most of the time the diaframe is dryrotted and they wont work.
Got a picture? I have a chrome "mileage-minder" but it is merely an aftermarket glass sediment bowl type fuel filter from the late 50s.
I don't have a picture, but they were round, chrome with a green face, and had a dial to set the desired pressure, inlet and outlet were, I believe 1/8" pipe thread.
I have a Model 500 Milage Minder from 1963. It has a glass bowl type filter like an AC or Carter filter assembly, but it's vacuum actuated. It must have been one of those gas saver gizmos that you could order from the back of magazines since the box is marked "advertised in LIFE"! According to the very scientific looking performance graph included in the literature, the Milage Minder regulates the output of the car's fuel pump from 1 psi (at full manifold vacuum) to full output pressure (at zero manifold vacuum). It looks like it'll work alot like the Cagle regulator I have.
I think you will find ads in the back of many 1950's HRM's, Popular Science, and similar magazines. They ran in the "This was the greatest car ever built, so the big Detroit companies put them out of business" crowd, who drove Studes--Checkers--Corvairs etc. and bought Judson Electronic Magnetos and every patented vacuum leak device and baroque distributor rotor advertised to make their whackomobiles even more superior to big three cars.
I have one and ran it on a mild 2x2 early motor (15 years ago). It seemed to function fine. They are orange in color aren't they? Seemed to be a quality part.
