Vacuum Pump

Vacuum Pump:

The vacuum pump is used to apply vacuum to a component during diagnosis. Such as applying vacuum to the EGR Valve diaphragm. The gauge on the hand vacuum pump indicates the amount of vacuum being applied. The gauge may also be used for testing purposes separate from the pump.
