Fitting water and vacuum pipes behind dash

[mach2andy]

With my car in it's current state seemed the obvious time to fit those pesky behind the dash pipes. I ordered a stainless set of water pipes from a major supplier and I have to say they fitted perfectly with only minor fettling of the holes with a 3mm drill. As you can see, I lagged them first. I was going to glue the lagging onto the pipes but it dawned on me that the heat from the water would probably soften the glue so I secured the insulation with tie wraps. You can see from the pics that once in situ, I held the pipes and their fixing flanges in place using Cleco skin pins which made the whole operation very much simpler. Thinking it was going to take me a whole day accompanied with much profane language, it only took me a couple of hours in the end, and was fairly straightforward. Maybe I just got lucky??

Nice job Andy,
Can you tell me what you lagged the pipes with exactly. I have been contemplating what to use for my new pipes. Currently I have used standard plumbers foam insulation, which I have cable tied tightly every few inches, so as to reduce the overall diameter, as I am aware the lagging needs to be a smallish diameter to prevent it fouling the lower vacuum pipe. If that makes sense!
Many thanks,
Rich

Rich, my suggestion FWIW:

I chose this as it's thin but looks like it should do some good, even though its designed to keep heat out rather than in.

Hi Rich
I used this from Toolstation. I didn't want anything too thick in case it made fitting more difficult, or possibly foul the wiper mechanism. My new pipes came with a set of flange plates, but I used my originals as I'd already cleaned and primed them. So my new ones are going spare if anyone wants them?

The screenshot isn't that clear. The thermal wrap is Toolstation item 67097.

Thanks gents, that’s great. I hadn’t come across these options in my searches.
Cheers
