cruise control pump testing

[Stickboy42]

hi all,

trying to fix the cruise on my 98 obw and have made it to the pump. testing the pump on the bench reveals that the 2 valves sound like they are actuating and the pump kicks on when jumpered with 12vdc. However, there is no or very little (not enough to move the throttle cable on the car) from the pump. I'm imagining that this is not normal and wonder what i should see for vacuum. The pump sounds fine just no vacuum. This is with the small hose removed and direct out of the pump.

 

anyone have a used one they want to sell if this is my problem which i'm guessing it is?

 

thanks again,

mike
