Yeah, you're probably not far wrong there, Dibble!
Tonio, best advice I can give is go to a local hydraulic hose place (look in yellow pages directory) and ask for high temperature hose. Should cost you less then 10 pounds.
Keep in mind, though, that should you turn up with these on your can in a DesmoDue paddock, be prepared to be ridiculed.
