Editing Z31/vacuum lines php (section)

== Z31 Vacuum Lines under the hood ==

This page includes lists and diagrams of vacuum lines for the '''1986 Turbo (MT)'''.
Any differences between models should be minimal, though they may exist—especially as additional
control items were added in later years. The diagrams should be very helpful with vacuum diagnostics.

Lengths are approximations, rounded up to the nearest inch, based on the hoses routed in my car at the time of measurement. Except for the vacuum pump lines, all of the lines installed in my Z were stock.

Upon replacement, I modified the lengths on the
front gallery lines and A/C lines to minimize cost and hose usage.
If you find that stock lengths—or your modified routes—differ from what I’ve listed,
please [drop me a note](mailto:sales@xenonzcar.com)
so we can compare.
