Missing vacuum line or not??

[kennyz]

Bear with me, I can`t take pictures but will try to describe this as best as I can.
2000 SSEi. There is a vacuum operated switch(?) on the front of the motor on the drivers side. It has an electrical connection and a line that goes to an arm that goes into the upper intake. There is a vacuum line that comes from the passenger side. There is also a nipple that has no line on it and I can`t find a hose anywhere to go to it. Is something missing or is this the way it is supposed to be??

Sounds like you're describing the Supercharger boost control solenoid http://www.pontiacbonnevilleclub.com/fo ... id#p211246
On the passenger's side of the valve, there is a single vacuum hose attached to it that also goes to the fuel pressure regulator, a vacuum fitting under the s/c snout and the MAP sensor..
On the driver's side of the valve there are 2 fittings; 1 connects via a vacuum hose to the boost control actuator (the part directly above it)
The other fitting should have a foam filter which usually just disintegrates over time

Thanks MKMike.

That answers my question perfectly.

This may seem like a stupid question, but does it matter which nipple that hose is on??

I don't think it's a stupid question. Yes, it matters.
The one with the filter is designed to be a vent.
The port with the vacuum hose is designed to apply vacuum to the boost control actuator.
The port for the filter has a retaining clip on it.

Thanks.

Agreed.

My boost solenoid has a vac line connected from bottom port (Drivers side of car) to the bottom of the boost actuator (thing with arm, kind of like a wastegate). then the other side of the solenoid (Passenger side) connects a vac line to the fuel pressure regulator. there is a vent on the top drivers side of the solenoid (mine has a foam filter on it but if its missing it looks like vac line is missing).

look at pic on this link..
