- Vacuum pump output is transmitted to the EGR vacuum bypass solenoid and brake vacuum booster, systems through a supply hose. The hose is connected to an outlet port on the pump housing and uses an in-line check valve to retain system vacuum when vehicle is not running.
- Pump output ranges from a minimum of 8.5 to 25 inches vacuum.
- The pump rotor and vanes are rotated by the slotted pump drive gear which fits into the camshaft drive gear.
