There's another line that comes from the left side of the engine compartment, through the canister and hooks up to the other nipple you see there with no line
It's little plastic check valve that is sticking out of the back of the lower intake that has a vacum line attached to it. ill get a pic in a few minutes
looks like this, but with a bend on that vacum line to go towards the fitting in the first picture
The red & green feed the EGR and one the nipple. the small hose sticking up feeds your FPR. The one out front feeds the purge soleniod on the firewall.
The big connector takes a 3/8 hose or so...it feeds to the vac tree on the drivers side inner fender... Your upper is the bottom line feeding this tree.
Been years since I had a stock intake...your talking a stock intake, correct??
thanks rio last finishing touches will be done in a couple of weeks i will post picks of my rebuild and let everyone check out my freshly clean and uncluttered engine bay
