there was a vacuum line on the back of my LS1 intake for the climate control. however this vacuum hook up is not on the back of the LS3 intake so where do i hook it up too now????

There is a vacuum connection at the rear. It is right next to the large vacuum elbow for the brakes. In most cases it is sealed. You just cut the plastic tee from the end to open it.

you could always put in a T back there off the big vac line too.

the ls3 stock intake should have a port from the back

when I installed the FAST102 there was no port in it, I need it for the engine vacuum pressure for my NPP mufflers

so what I did is making a T back and put it in the brake vacuum line
