Idling Problems

I need your help. The PVC hose on my VX is disconnected from the engine. I have an SC installed, if this makes a difference, to the place that the hose should be connected. I know that it is connected on the back of the SC or some place close, on the back of the engine. The symptom that I had was Idling problems, the problem was to low idle, the engine turns off at any time.
If you have a picture or drawing I will appreciate it, since there is limitted space to work and to see a picture would be great help. Thanks.

PVC hose must be connected to the fitting on the back of the SC, pointing down in order for it to idle.

Thanks Tone it's fixed. :)
