vaccum lines

Do you have Autolite 25's ? If so gap them to .042 and set fuel pressure to 38. Try bumping your timing to 12-14 degrees with the spout out, while driving under a load listen for pinging! If you get a ping back it back down a degree or two. As far a vac. lines go my exploder intake only has the pcv, the brake booster, the fpr, and a boost gauge on it.

Vacuum line connections:
One large vacuum line from the upper front goes to the carbon canister

One large vacuum line from the rear goes to the vacuum tree.

One small line in the front feeds the Smog pump solenoid control valves on the rear of the passenger side wheel well..

One small line in the rear goes to the fuel pressure regulator.

One small line in the rear goes to the EGR suction regulator.

One large line in the rear goes to the PVC valve.
