Looking for Vacuum diagram for 2008 5.3L Vortec

[JBenny1]

I have a cammed 5.3L Vortec and previous owner told me he removed vacuum line and i was wondering if anyone new where to find a diagram and the reason one might do that

[davester]

might find something on charm.li IDK what else besides the brake booster would be getting vacuum, perhaps the fuel system?

There is only 1 real vacuum line on those trucks technically.

 

The brake booster vacuum hose. The other "hoses" are for the PCV system. There is a barb on the drivers side valve cover to the top on the intake manifold and there is a passenger side bard that went to the factory air intake system. Nothing else uses vacuum.
