I should know this... but my manual is out of reach at the moment and this is driving me nuts. There's a vacuum line (clear-ish) that comes through the firewall above the brake booster, and runs over the valve cover at the back of the engine. Mine is loose. Where does the damned thing go? It must have popped off while I was piddling with the air filter.

Thanks!

That should go to the banjo bolt on the rear side of the manifold.

DOH! Can't believe I didn't think of that. What the heck does that actuate, anyway?

Thanks a million!

It goes to the over-boost protection thing-a-ma-bob that is mounted on the firewall... From there it goes to the side of the ALDA... a bit left of the power brake booster.

Here is how it needs to be routed.
