have a quick question, if you remove all the emissions and junk you are left with brake booster vacuum line and the fuel pressure regulator line, right? so i got the brake booster part down but then where do you plug the FPR line into if you remove all the other emission lines?
i think im missing something....
thanks

the fpr is on the end of the fuel rail, there will be a vacuum line and a gas line to it. Or if your asking where to get vacuum from there is a 90 degree angle line on the back of the lower plenum to run the line.

i know the fpr's lines but i was removing emisions and all that other junk like the swirl valve and the other valves on the back of the head, so if those are removed your saying just plug it in to the plenum? whats the plenum is it near the back of the intake near iacv?

thanks for the answer i really appreciate it im rebuilding the motor and at a stand still due to this.

Maybe plenum wasn't the best choice of words, but on the lower half of the intake manifold there is a line that comes out. The pic came out pretty crappy, but right above the hole for the iacv you can see a nipple that comes out and turns 90. Pretty much right next to the brake booster outlet.
