Wiring loom - clothing cover replacement - Tesa heat resistant isolation linnen tape

Whilst I was doing the fuel hoses, in between I also tackled some wiring insulation. I don't expect anyone knowing or remembering this but shortly after I had bought this car a small explosion with fire occurred, see this blog:

As a result some of the electrical cable harness had minimum or no protective cover left, not the plastic but the clothing insulation, not sure what the appropiate name is. For the XJS they used apparently a brown colored material. And due to it's age and heating it's mostly detoriated and can be easily peeled off:

Recently for another car, Lancia Kappa SW, I have done a similar exercise:

So I had still a bit insulation tape left I could use. So that's exactly what I did. I freed up the cable and removed the old insulation cover,

And covered with new "tape". Such an easy and rewarding job. 

And another small section I had done:

So for now the most impacted and visible wiring looms has be done. I only did these as they were next to the fuel hoses I was upgrading. Doing the entire wiring loom in the engine bay is a huge task. For now this was an easy and quick fix in between and I also could finalize the fuel hoses. I will consider the remaining parts or other visbile cables for another time.

All looking good again:
