If you can't source a decent second hand one I would imagine a company that makes hoses would be able to make up something suitable, one I've used before for various hoses on my aircooled VW's is Pirtek, they have branches all round the country and they have always been very helpful, nearly all of their pipes are able to handle high pressure as well as the ends are properly swaged on, worth a call if you can't find anything else
