82 380SL vacuum attachment point help??

[rstarkie]

I took lots of pictures and notes during the disassembly of the top of the engine and it has gone well in reassembly except for one vacuum line. The yellow in the image circles the component on the driver's side of the intake and the red points out the vacuum line that is 12 inches in length.

One of my photos seems to show it running on the under side of the manifold, but I can't be sure.

Can someone help me out on where that line attaches?? Thanks in advance.

That's not a vacuum line, it's a "just in case" line. The component is the pressure regulator for the fuel injection system and the line goes to the vent hose for the valve cover. If the diaphragm breaks and it start leaking fuel, that line directs it into the valve cover to be dumped into the oil, rather than spraying across the top of your engine and causing a fire.

No problem, I had the same question when I'd just gotten my car. Someone was nice enough to answer me, I'm just returning the favor.
