Thanks Craig.
I think I’ll trick a friend to come over and put the vacuum
reservoir back in place.
I’ve had enough of brake pedal boxes for this lifetime.–

The metal can is a vacuum reservoir. It is needed for proper operation
of the brakes, climate control, and cruise control.
The hose in the pic above is likely a plenum drain from the AC to allow
the condensate to drain. Otherwise you get wet feet!

G’day Vikram,
That little bit of hose with the clamps on it looks to me like part
of the transmission breather setup. Yours might have come adrift.
Is it connected to anything? Do you have other pictures of it?
The aircon plenum drains were just a rubber hose sticking through
the side of the transmission tunnel with no clamps.

As for #2, Vikram; it is the vacuum cannister for the AC system…
The vacuum line is connected to a ‘T’, one branch goes into the car,
connecting to the AC system. The other goes down to a one-way valve,
which in turn is connected to manifold vacuum…
#1 is more obscure - having a clamp at the end it seems meant to be
meant connected to something. But it may just be the AC drain as Craig
says - backtracking it may clarify…?

thanks everyone.
I think I asked this before but didnt get an answer. Are the
12 metal intake manifold gaskets re-useable? I want to put
the car together, but if I need new gaskets, I’ll have to
wait another week or so.
I was reading the Haynes manual on doing some transmission
servicing and saw the stall test. Basically its having the
car in Drive and foot on the brake. You’re supposed to look
at the rpm to tell whether the gearbox is alright or not.
They say not to do it for more than 1minute every half hour.
Now isn’t this scenario exactly what happens when you’re at
a traffic light? Surely some intersection take more than 1
minute to change.
Does this mean on a BW transmission, you have to put it into
Neutral when stopped at a traffic light?–

No, because while waiting for a traffic light you are not applying any
throttle.
Performing a stall test involves applying more and more throttle, with the
transmission in gear and foot on the brake, until the engine rpm stops
climbing (“stalls”), usually at around 2000 rpm. This creates tremendous
amount of heat which can damage the transmission, thus the warnings.

Not at all, Vikram - as Doug says this is a specific ‘full load’ test
only procedure of the gearbox’s innards to detect some anomalies…
With the engine and gearbox fully warmed up; floor the pedal and read
the rpms. The completel warning reads; not to run the test for more than
10 sec at time and no more than a minute in total any half hour. Point
being, as Doug says, to avoid overheating the box - so repeat runs
should allow time for cooling. Between 1950 and 2100 rms is ‘normal’…
Repeats are really not necessary; once is enough to get the required
information - unless something is done to the box in between. And there
is nothing really to be done in between…

The test procedure in the Haynes manual says nothing about
pressing the accelerator. It actually specifically says
‘‘depress the accelerator’’.–

The Jaguar manual, referring to the stall test, says; ‘fully depress the
accelerator’, Vikram…
…and instructions also includes full hanbrake and foot brake
application. This is a combination of actions that is most unusual while
waiting in traffic - which makes the difference for the gearbox in the
stall rest…

How curious! But then one could be forgiven this mistake since we
do have declutch, degrease, decode…
But then whereas we do hear of the occasional engine being
destroyed by overheating or a dropped valve seat, I have not come
across one being ‘stroyed’ back to health.–

I thought depress was the opposite of press.
Now it makes sense.
