Hey Lads,

Wanted to drop a quick repair hack on you in case no one has ever done it like this before.
It was a repair I did some time ago but wanted to make sure it had long term legs before suggesting it to anyone else.
It was the first time having the issue with a cracked, corrugated hose on the XK8 and I wanted to see what could be done to create a decent long term fix.
IN removing this hose to work on other things, the plastic split (of course). Being plastic, time is going to have this effect and it might be noticeable and might not but eventually, there will be codes thrown because of it.
So, I started this repair by using some superglue to apply to the crack itself which was about halfway around the hose. This held the hose together so I could put the real fix attempt to it. Of course, the hoses need to be airtight, so my second step was to apply some YamaBond gasket sealer all the way around the repair area. YamaBond and similar grey sealers have the ability to flow into the grooves of the part and makes it an excellent sealer for things like this, but the sealer would not be enough to say it was fixed.
The next - and final step was to use some heatshrink tubing to cover the entire repair area which would provide the strength to the repair, allow for some additional sealing and finally, look stock-ish when finished. I chose to use heatshrink that itself was of the sealing type and you can find shrink like this online with a little searching. I think it was half inch tubing but do not quote me on that because I forgot the exact diameter of the tubing I ultimately used.
So, this was a small repair that has held up nicely and I think it could be applied to the entire hose effectively to completely encase the hose and protect it from getting cracks in the future. The next time I have a cracked hose like this, I am going to cover the entire hose to see how that works out.
A couple of additional tips would be to apply the heatshrink tubing before the YamaBond has completely cured. This allows the tubing to squeeze down on the YamaBond and form to the shape of the hose. Another tip is to apply heat (use a heat gun for sure) to the inside corners first if that is where the crack is. This helps the shrink form more easily to the corner using all available material and then the outside gets heated to simply allow it to pull up whatever slack is left in the tubing.
I applied a double layer for certainty of the repair on mine. Not sure if I needed to or not. You could also have some fun using colored tubing to provide a little color to a repair that needs doing anyway. I did the repair several months ago and it is still perfectly fine.
