I am fabbing a turbo kit for my GFs TC and started this morning , everything seems to be goin well so far but I have a question . when I removed the stock airbox there was a green plastic valve next to it , and it says 1psi . well what is everyone doin about this valve ? thanks

 

DO you have photos of this valve? This might be the low pressure fitting on the Ac system

 

I think this is the valve that send fuel vapor from the gas tank back to the engine? This is the ticking sound you hear when the tC is idling.

 

that is the one , how does everyone go about keepng it ? do I need to change anything ?

 

bump , anyone

 

you keep it. Don't pay any attention to it.

 

thanks prototype .
