I am working on replacing the vaccum check valve in the HVAC system right by the intake manifold. When I removed the old check valve I forgot the direction that it was setup. Can someone help me with which direction it should be. I currently have it flowing into the intake manifold. Is this correct?
Thanks Moparite I got one from Napa as my current check valve didnt work well but it didnt have any direction on it. So I blew thru it to see which direction it should flow.
