12v Electric Power Brake Booster Vacuum Pump
This pump is used when your engine does not produce enough vacuum to allow your brake booster to work properly. Recommended for cars with 15"lbs of vacuum or less at idle. Pump hooks directly to your booster to provide proper vacuum needed. Kit includes all wiring, vibration isolators, hoses and hardware. Self adjusting inline vacuum switch cycles the pump on and off as needed to allow the pump to run only as needed.
