Just picked up an 85 DL and the 'how to keep your subaru alive' manual. It didnt run due to a clogged exhaust. Its fixed now. It's running ok? My question is: someone has been playing with the vacuum lines. Id like to know what is the minimum required, no Emissions here, and what they were supposed to be originally? Thanks for any assist.

Only three needed. One for disty,one for heater control and one for brake booster. Been so long since i got rid of them i dont remember what the other 12 or so do. Just drain power if you ask me! I even got rid of pcv and that little metal tube that goes from right head to intake, Couple of pipe plugs did the trick. So now with Holley 5200 carb and no cat i can feel a big differance in power. I can cruse at 75 in fith gear and still pick up speed if i stomp it to the floor
