Hello,

I had a question, I have a HKS sport upgrade kit in the FC, and comes with a dual nipple actuator diafram.

something like this.



I had understood that the first nipple sees boost ( comming directly from front cover and second nipple is for the boost controller- wich at this moment is not installed) So i left unconnected.

I was wondering if anyone has hooked up one of these dual nipple diaframs and how.


2nd question, If it is hooked up correctly , then maybe Its pooched. I tried with a vaccum tester to find out if either nipple could hold vaccum but none could, Tonight when I get home i will try with the aircompressor , is there a way to check if it works other than aircompressor and giving it say 10-15 psi ) .

Thanks


edit:

Im saying this becasue the WG did not open with boost with the nipple closest to the front cover connected and the othe rone disconnected .
