There is a vacuum hose that connects to the left side of the throttle body. I can hear a slight hiss at idle. Maybe the line is cracked. Anyone have a part number for this molded hose? I cannot locate on a PET diagram. Thanks

It could also be the o-ring that seals this line to the plenum. #14 O-ring at ACE hardware

BTW - O Ring looked OK after removal, going to spray water on line to see if hiss deadens. If no, I will order the part. Good information and thank you for the quick response.

Interesting. My supercharger setup has this port capped off so the hose that used to go to it must be connected somewhere else.

Engine Ventilation Line, Distribution Part No. 997 107 145 02 purchased @ Pelican and installed. I noticed the line I removed was slightly cracked and brittle.
