I'm new to this forum and this is my first of many to come post. Was wondering with the greddy bov were do you run the vac line to off the side of the bov. and also there is a small port coming off the underside of the bov. Would like some help, --Thanks

 

tap the vacuum line into the line that comes off the tb. as for the other part of your question, i think you're referring to the second nipple on the bov, don't worry about that it's for a recirculating set up.

 

cool thanks, the other nipple does it need to be plugged or just let it vent?

 

just let it vent....
