I need help to determin boost leak
<center><img src="http://pictureposter.audiworld.com/71765/dsc_0002.jpg"></center><p>I did pressure test today..
and find really small leak..
really quiet hissing noise at 12-14psi
from somewhere in this pic (circled)
it's somewhere where fuel rail. is
anyone can guess? or could it be where injector is? (like bad o-ring)

Pressurize it, and put some soapy water in the area... it will bubble where the leak is.
An injector does not see boost pressure, so that's not it.
Try wiggling the hoses and listen for a pitch change...
