Other 2005 L320 RRS vacuum pipes part no’s

Hi all,
I‘ve been eliminating air leaks on my 4.2 s/c RRS and was running a smoke test on the throttle body yesterday and discovered smoke escaping from the base of the two pipes at the rear of the throttle body (See pics) one is hard plastic and runs to the top of a t-piece leading to the brake vacuum pump (see pic) the other is a softer rubber pipe running to (not sure but there is a pic!) Always looking for opportunities to spend I eagerly dived into the online parts catalogue and had little success

I can Find the exploded diagram of the vacuum pump but am not convinced the pipe I need is shown as the pipe I need seems to push fit into the rear area close to the throttle body/top of s/c and it has a click-fit connector to the top of the vacuum t . I can’t see anything like this in the parts manual - I think it’s the part that I’ve arrowhead in the pic- but there is no part number for that.

As far as the rubber pipe goes - I can’t find anything - probably as I’m not sure what it’s function is.

A final question is - how do I remove the had plastic pipe one end easily unclips but the leaking end seems just to be pushed into the housing, it moves a little up and down , but I haven’t wanted to be too vigourous!

all help gratefully received!

Hi all,
I thought I'd answer my own post on this one - just to share the knowledge:

I got in touch with JLR classic and asked the questions.

They have confirmed that the pipe part number is LR018336 and that the connector in the elbow was only ever included as part of the Elbow that the throttle body sits on - the Elbow was part LR009386 cost £800 and is long out of stock

However... I have been searching on the Jag forums as a dual brand owner - and apparently the seating for the pipe is identical across a number of Jaguars and is part number C2S15816 - A Brake booster vacuum hose connector kit for a number of Jags

It comes with the connector and sealing ring and for £18 I thought it was worth a pop direct from JLR - will advise if it fits and more importantly seals!

Forgot to confirm. It’s a perfect fit and leak was solved
