Ali Express : 6PCS BRANDSTOFINJECTOR VOOR JAGUAR DAIMLER XJ12 XJS V12 5.0 HIJ 82-89 D JETRONIC 0280150035

By surprise I bumped into this offer on Ali Express. Not sure how good the quality is but this is a bargain (well, pending on the quality of course). by the looks it does come with the fuel hose as well. Not sure if it does include the additional furele's. Does anyone has experience with these?

Boot cleaned up and put everything back again

Over the past few years the boot was still not organized. At the time I had the complete fuel tank taken out, whilst the tank was cleaned and put back. The boot was a mess and serving as a temporary storage for several parts and such. So now finally time to organize it and put the carpets back in, the battery compartment build up (metal front cover, battery strapholder plus plastic cover box), fusebox cover and mount the spare wheel again. I was pleasantly surprised to see the spare wheel had a nice cover included, totally forgot about that. Also I have the jack and toolkit included in the side pockets.

This looks so nice and tidy again. Still I can consider to clean the carpets a little but that can wait. Should have taken a photo before as well:

Basically this means the car is now fully build up again and almost ready to drive again. I still want to work on a couple of items though but so far so good.

Front spoiler + cover plate + grille

 Another thing I had to mount back was the front bumper spoiler and the cover plate:

This reminded me I also need to source a decent front metal cover plate as that one is seriously rotten. Luckily its an item that can easily be removed and replaced (if I can source a good one):

But the grill also needs attention:

Not sure how this is suppose to look like originally. Is the outer trim chrome or polished aluminum. Or should it be entirely in black paint? 

It's now all fitted back but not entirely to my liking, the three bottom pins in the grill shoud fit thru the spoiler but there is to much space. 

Meanwhile I also looked up the bottom plate, difficult if you don't know the appropiate name or part number. But the good news is, I found it and it's available, still a bit pricy so hopefully I can source an affordable used one.

And the part nr is: RTC1531 (front lower panel valence)

Knowing this informatio it helps to narrow down the search.

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:

https://erwinxjs.blogspot.com/2016/08/engine-caught-fire.html

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:

https://erwinkappa.blogspot.com/2025/08/wiring-loom-heat-resistant-insulation.html

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:

Fuel hoses replacement - part II

Next to the fuelrail injector hoses I have done the remaining fuel hoses replacement the day after. Only compiling this blog post today.

Check out the next video by Living with a classic:

https://www.youtube.com/watch?v=divOwQVFLFA

The first part starts again with the fuelrail hoses but at around 15:40 he starts explaining the other fuel lines that requires replacement. He only demonstrated the tiny one.

The exercise is more or less the same but these ones are a lot more easy to carry out

And using the additional fuel hose kit with clamps

Yes, this one needed to be done badly

Cut it off and in the bench:

Use the hacksaw and it saw it open

And the same process for the other side:

Mounting on the new hose with clamps

And put it back again:

So on to the next one, which is also fairly easy accessible:

And the same process and another one finished:

The third one requires more effort but still very doable. It's twisted under the manifold and at both ends I cut it off in order to remove it gently and not damage antyhing with force.

And the other side:

Still firmly attached, so it had to be carefully cut off:

And here we have the entire pipe visible

And again, it needed to be done badly

And another 1985 tag ... strange

And refurbished

And back in again

So the next one was going from a pressure valve to the main fuelhose connected to the gastank

However it's in 2 parts. The last part is using a thicker fuel hose via a connector. Not sure why this is?The other side is having one fuel return hose (from the cooler unit) with no connector in between but it's a slightly thicker hose as well. 

If I had to replace both these hoses with the provided hosekit it would mean I would run short on the provided hosekit (lengthwise) and only 2 clamps are left. So likely I only need to replace the part on the main fuel inlethose. I left it for now but will look into this next time.
