    97 GTP, noticed that the nipple for the vacuum line on the supercharger bypass actuator coming from supercharger bypass solenoid is broken off. Anyone know where to get a replacement? Part #?

    Looks like it has to be ordered from zzp

    Is it possible to glue the hose on for now somehow until the part arrives?

    Many unplug that port anyway. The solenoid cuts the boost and keeps the bypass valve open when your traction control kicks in from reduced traction being detected. If you don't care about that then you can still drive the car and order a replacement if you want. Junk yard may be a good place to pick one up cheaper then ZZP or the dealer.

    Just so we're clear, the broken nipple is marked with the red X on this diagram.

    your best bet is to take the vac line off that runs to the BBV solenoid and unplug the solenoid. all the BBV and the BBV solenoid do is cut boost when in reverse and when the wheels are spinning. its not necessary. here is a picture of how mine looks:

    the first picture is how it should look when you do the BBV solenoid delete, there are other's that I took before I figured out the right way to do it.

    This wouldn't have anything to do with my awful mileage would it?

    it could if you have a vacuum leak. any unmetered air coming in is going to make your car run rich to compensate.

    try doing the BBV solenoid delete and see if it makes a difference
