In this pic, you can see both tubes. The bottom oem tube, if you look to the right of the tube, you can see the foot that gets bolted down, then right beside it is a vac line nipple. Then if you look at the top intake tube, you can see the foot but to the right of it is no vac line nipple. I basically just tapped it, used a 3/8's drill bit, used my dremel to slightly smooth the hole, cut the stock oem vac nipple off, and tapped it into the new intake with a dab of black rtv. I would test fit it first and mark where you want to drill so you know where that vac line comes up too. If you go to far up or over, it might not reach since the line isn't that long. Though the fix then would to be cut off the vac line connector, and use a rubbe vac hose to make it reach. But the way I did it is so you can retain the factory style connector.
