Vacuum Pump

67Dart273....do you have an idea then of what we need??? Thxs for the info on the Vacuum Amplifier

Not specifically. I know there are options for both electric and alternator driven pumps off diesels, all expensive.

Years ago, on older cars with vacuum wipers, you could get a "dual diaphragm" fuel pump, actually two pumps in one.............one side pumped fuel, the other was vacuum for the wipers

So you might "gamble" and use an electric fuel pump, then use an engine mount fuel pump as a booster. Not sure that would work

Frankly, I'd think about eliminating the booster, as said above. I just got through converting my 67 to front 73/4 disks, along with the disk brake Versailles rear axle.

I just used the original master!!! by running a nail through the rubber seals on the residual valves, and it just works great. My legs are not that strong anymore

If you must have a booster, you might look into something like----my neighbor is going through about a 69 'Stang and it has a TINY (diameter) booster.

If you have PS, look into "hydro boost"
