towards the back of supercharger towards front of the car there is a hose missing...the other one goes to black soloniod that goes to top of supercharger,where does that hose go? do you need a pic?

Pics are worth a thousand words.

whats the black unit above it,I checked the vacuum to it and it does not hold,friend says its no good if it doesn't hold.

Nope, that'* suppose to be like that. It'* so that the boost control actuator can bleed off. Mines the same way.

In this image, you will see that there is actually a piece of filter on the nipple...




Much like what you can see what'* left on yours.

what about the black unit?

Boost valve actuator.

Note its position with engine off. Then start engine. If it doesn't move up, then there is a vacuum issue. If you use a vacuum tool to put vacuum on it, and it doesn't move, then it probably has a hole in it or the arm is seized.

I put vaccum to it and it did not hold it.

it does move when the engine is running..so I don't know..i get a hesitation lately..thought that could be it.

If you disconnect the black hose to it, connect your pump to it and pump it, its suppose to stay put.
Another way to do it is to disconnect the hose, manually push the actuator in, put your finger on the hose nipple and let go of the actuator. It should stay. If it does not, then the actuator is bad.

that vacuum line looks terrible, i would replace any that look like a dry rotted old tire, they get stiff and dont hold vacuum long before they look like that
