David,

The line is a ten minute job. There are fittings on both ends, I think 19MM. Just wrench them loose, remove the vacuum lines from the tees, wrench on the new one and replace the vac lines on the tees.

Palangi offered the correct warning though. One of the tees in the original line had an orifice. Some of the replacements have no orifice on the front tee, they are wide open, too much vacuum. Others are closed off and must be drilled out with a 1/16th " bit.

Good job,
