Craig, many thanks for pitching in, I have now found one in the good old US of A. Hopefully it will be here by the end of the month.
Colleyv12, yes it is different, about 50mm longer than the 24v version (as I found out today!!)
Ian, many thanks for the original post.
Lastly, I should mention the mysteries of plastic welding, some friends have a bodyshop (they painted the car) and they 'plastic welded' the hose today, adding plastic to the tear. It might not be a permanent fix, but at least the car idles & runs properly, and hopefully will last until the replacement gets here.
