Vac lines information.

I have found 3 images of how the vac lines are supposed to be run after the rats nest removal.
The problem is each one conflicts with the other 2.

maybe someone can clear these all up.

No, they all are simular, except for #2 does not remove the Purge control and #1 does not have the charcoal canister.

IMO you need the air bleed lines, FPR line, pressure sensor, and switching actuator line (if keeping the stock turbo set up) and bypass (BOV) lines (all as shown in all the pictures).

As far as the purge and charcoal canister... well technically the car would run fine without them, but I might do a catch can if this was a street driven vehicle.

yep that's it, but be aware that no block-off plates set include the cold start assist system in their kit

So you're gonna have to custom fab one

Actually the block off set I got off of ebay had that one included.
It was like $35 for the set.

That's the Sub Zero Starting Assist system. Free fsm's are avilable on the web with graphics.

3mm aluminium plate. Hacksaw or jigsaw. File or bench grinder. Drill. A very small amount of skill. Half an hour. Problem solved...

There is a tube attached to the BAC valve where coolant goes through. But if you remove the BAC valve itself, it will leave 2 huge holes open. This would constitute a huge vacuum leak.
