on the intake manifold, use the part that part that sticks up and used to hold the stock filter.u can drill about an 8th inch hole all the way through and then use a 1/4 inch nipple with hose barb. drill and tap to the right size.

It is a vac. only when the intake valve is open when it closes there isn't one giving you a pulse. The intake is the best place to get the pulse because if you tap into the crank case there is a chance of pulling oil into the pump and locking it up and conecting it to the intake the only thing that it might suck up is a few gas fumes and that will not hurt a thing.
