Where does the ACV vacuum hose go?
 

There is one vacuum hose coming off of the ACV and it either goes on the upper manifold or on the vacuum spider hanging off of the upper manifold. Right now I have:

1 hose running off of the ACV

1 nipple on the upper manifold

1 hose running from the pressure sensor

1 nipple on the vacuum spider

which ones pair up?

:confused:

Somebody has to know this. My guess is that the pressure sensor is the one on the manifold since it is only testing. And the ACV is on the spider because it is actually doing something, and all of the other lines associated with the ACV are running off of the spider.

You answered your own question.:D
