I've done some looking around and haven't come up with a solid answer.

How much vacuum line and of what sizes are needed to put new lines on after emissions have been removed and blockoff plates installed? 87 TII with s5 motor, s4 manifolds and electronics. I don't want to order the $100+ kits and have a bunch of extra stuff I have no use for.

I think it just needs 3.5mm and 6mm. Also does anyone know the same sizes/length needed for a 1st gen 12a after blockoffs? I have a friend that would like to order some and we were going to put it all in one order.

The summer is passing by quickly and I'd like to get my 7 situated, I've had it on the back burner for quite awhile (been waiting on a gasket from pineapple racing) They keep sending me the wrong one or forgetting to mail it out. Hopefully it'll show up by early next week. In the meantime I'd like to get my silicon lines coming. Unfortunately no local places stock the silicon lines, just turbo/intake couplers....

 

Looks like some 8mm ID for the brake booster, is that the only place that needs 8mm ID?
