Just replaced the cruise control vac diaphragm unit on our V90 and found that the other end of the vac line is not connected to anything. There was work done on this car and I can not find where this line might connect. I "think" there's a spot where some straight rubber tubing was installed that looks like it might be where this line "T"s in but I'm not sure. Not been able to find any info on line. Am hoping that someone here can give pretty clear directions to where this line goes. A picture would be great.

 

Give me a few days to buy this s90 and ill grab pics. If its idling, the suspected correct nipple should be pulling vacuum. If that's the only loose hose, the should be only one open nipple-in theory as long everything else is installed correctly. Take a BIC lighter with no flame, shoot butane at the suspect nipple, or Carb cleaner. If motor stumbles, you found it.

 

Did you solve this?
