Intake Manfold Vacuume Lines

Can someone snap some pictures of the vacuume lines coming off the intake manifold. Or a diagram would work too. I just installed a weapon R intake had to drill extra hole for all the vacuume lines, but now comfused where all the lines go

You don't really need a vacuum diagram per say, as long as you know what all the components are. Here is a list of all the vacuum actuated sources that need a vacuum line (Some will apply to you, some may not depending on how your car is set up):

1. Fuel Pressure Solenoid
2. Blow Off Valve
3. Brake Booster (Large line with check valve inside)
4. Boost Gage
5. Boost Controller
6. Fuel Tank Vent (Has Check Valve In Line (I think that's what it is))
7. PCV Valve
8. Turbo Wastegate (From Boost Controller)
9. EGR Valve (If its still enabled/there - Your case probably not.
10. Two small lines out of the top of the Throttle Body (Emissions related stuff I believe)

Thats all I can think of for now...

That kinda helps I am still confused...I think the EGR is the reason I drilled 2 holes. Does it have small vacuume line? Their is a lot you listed on my manifold it has 4 large outlets and now 2 small lines fron the thing I had to custom install. My goal is for it to pass smog
