[xj] Vacuum hose routing

In reply to a message from uncoded sent Fri 9 Oct 2009:

Got to be a little careful here because UK manifolds and vac
routing are different (among themselves, as well) but if there’s a
pipe on the underneath at the back, pointing straight down, it’s
the drain. Cap it with a short length of tube and block the end.

You definitely need a non-return valve in the line that goes to the
bulkhead.

See SKJagtech’s diagram : http://tinyurl.com/5f7ka9

Doesn’t show the nrv but gives a clue about pipe routings.–
The original message included these comments:

understand in Alex’s diagram though. I am still unsure what
the spigot under the intake manifold should be connected to.
His diagram has a ‘‘one way valve’’ in the line from ‘‘delay’’
to ‘‘delanaire AC’’ I don’t remember seeing one on my car,
just the valve with the 3 spigots.
