Thanks Hanno.
I was looking at getting some here.

It seems to be quite similar to the link Grant posted....hose used in aircraft and also for race cars. They also sell through a webshop and also just 1 meter in stead of 4.
I just can't make up my mind whether to choose black or the orange/brown stuff! The remains I found in my Chev are somewhat orange...but I am not sure if that's rust or the original colour of the hose. Black probably looks better though....
