Adjustment on an old HKS "super" blow off?
 

I have an older HKS super blow off that seems to have no adjustment on it. It has a top nipple and a side nipple. There is no screw or other fastener to adjust. I *think* i hear is leaking under boost but i am unsure. I am tempted to make an adapter to pressure the intake track to see if i am correct.

But the other thing is i have no idea what each nipple is supposed to be connected to too. And google has been no help.

HKS informed me that BOTH nipples should run into one signal line.
