OPERATION
Vacuum pump output is transmitted to the Heater, Electronic, Vacuum, Air Conditioner (HEVAC) 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.
