2 go to air pump, one goes to vacuum fitting on intake, and the green one goes to egr. I just plugged the 2 for the air pump with bolts, just in case emissions ever do get brought it I can hook it back up.
Dont mean to hijack, but do any of those lines have to do with brake vaccum, the reason I ask is I deleted my egr yesterday when I swapped my headers and now I have very soft brakes. I did plug up the green line by the way
Yup, used the gasket. Can Anyone point me in a direction on how to do a vacuum test? I'm going to buy a vaccum tool from harbor freight Monday but I wanted to get all my info right by the time I go pick it up.
