new motor is in, all bolted down. i'm hooking up all the wiring harness's. my question is about the vacuum lines. thr smog pump is gone and all the emissions crap. is there a diagram out there to show the best way to hook up all the vacuum lines. do i just get rid of everything and just plug up to the fuel pressure regulator. pcv valve, and break booster. looking for all advise. i did a search for "how to run vacuum lines" but couldn't find anything... i can't think of any thing else that would need a vacuum source. i plan to delete to egr valve... i guess thats it .... talk to you soon.........

1 Large Vacuum Line will go from the Vacuum Tree to the Intake (the Passenger Side). From there, 1 smaller Vacuum Line has to go to the FPR.

Then after that, there's 1 Line going from the PCV Valve that splits into 2 and 1 goes to the middle of the upper Intake, and the other goes to the Driver's side.

If you have no smog and no egr, then you're done :)

Oh yeah, and there's a little line coming from the Charcoal Canister, you want to connect that one somewhere to the upper intake, unless you deleted that also.

Tell me your intake type?
I just did this and deleted my smog .

If you need a quick fix.
You have plug the 2 smog sensor vacumes into each other.

Now the red and green vacumes are gonna go. red to intake and green to the egr.or vice verse,I believe red is intake.
The brake booster obviously .
The fpr gets its own vacume line.to intake. set it 40-42 psi
The pvc obviously
if you have no pvc ,then vent it to atmosphere
The little cylinder guy with a 2 prong plug near your maf corner has a vacume,its the purge canister,thats gonna go into the intake i believe.
And thats a wrap!
if you have the stock inlet tube ,then the inlet gets vacume

obviosly the tree on the drivers fender is still intact right?
set the tim,ing to 10deg ,prime up the oil pump simnce its a new motor....DONT FORGET THIS!
check for oil pressure immedialty!!! if none is visable SHUT IT OFF IN 2 SECONDS!!!!!
make sure you hook the oil sender wire up.
the engine temp
the intake temp sensor on the stock inlet tube if 94/95

good luck
