So I'm installing the catch can (finally) and the "y" hose at the throttle was somewhat broken. The venturi tube was rotted, cracked and broken. I'm in the process of fabricating a new tube, but need a question answered:

How far does the venturi tube protrude into the throttle? Going from Rob's pictures on the CC install, my fab puts the tube about 1/4" past the inside wall of the throttle body throat.

Thanks All...
