His vacuum line thread was wanting to know how to properly connect all the vacuum lines on a '72 318 because his son's car was down until all the lines were connected. Would have answered but all I know about it from the day was pull the line off, give it a squirt of RTV, install a BB, and reinstall the line. Do this to all the lines except the distributor advance and the brake booster line if so equipped. He didn't act like he wanted to hear run a distributor advance line, a brake booster line, and cap the extra vacuum ports, so I left it alone. Besides, a car guy would know to do that anyway. Sorry he got his knickers in a wad over it.
