Mr Gasket 3701 Details

Most vacuum operated brake boosters require 18" of vacuum to operate correctly. This vacuum canister from Mr. Gasket offers an additional reserve of vacuum for vehicles equipped with vacuum-assisted power brakes. The vacuum reservoir can only hold up to the maximum vacuum available from the engine; it does not create any additional vacuum by itself.

  • Black painted steel finish
  • Ideal for cars equipped with big cams and power brakes
  • Improves brake performance
  • Connects inline with your existing engine-to-booster vacuum hose
