Installing a Brake Vacuum Pump In My 1961 Impala

If you modded your car with a bigger engine or more aggressive cam you may find your break vacuum has been diminished - mine dropped to as low as 9" (or Hg). Typical should be 17-22Hg - so I am installing a brake vacuum pump which will get my vacuum back up to 20.
