Vacuum Harness/Vacuum Pump 1

[Avi586]

Could anyone advise me how vacuum harness and vacuum pump works with bypass valve/EGR valve?

i have been asked to start a new project on Vacuum Hose but i am not familiar with this subject could any expertise advise me or guide me please

um, we might need a better starting point than that. what _do_ you know? what are you trying to do?

Some EGR valves are vacuum actuated - they have a diaphragm which is exposed to manifold vacuum on one side and air on the other. Vacuum hoses connect from the manifold to a solenoid, and then from the solenoid to the valve. When the solenoid opens, the vacuum sucks on the diaphragm and opens the valve to let EGR into the intake manifold.

That makes sense. I think I know what I can do now. Thanks.

Just curious

Is Avi586 and Kangaroo Pete the same person?
