Hi Gareth, thanks very much for the reply.
When I've looked into the same part number with a different suffix letter at the end it's always been a different hose - looking at engine diagrams with part numbers, the engine has different hoses with the same part number but with a different suffix on the end.
Looking on UK eBay I have managed to get a second hand hose from a vehicle dismantler, although I was really after a new one - the one I've bought is the same age as the one on the car so I assume just as 'aged' or 'perished' as mine and as likely to leak (mine is basically leaking from the ends of the hose, I assume where the clamps are no longer tight enough?)
I have looked at vehicle parts suppliers in the EU and found the hose in their listings, but none of them have stock. However, I haven't looked at eBay International, so will take a look thanks.
Another option I was thinking about was to get a custom silicone hose made up and that was the main reason for buying the second hand hose from eBay - for use as a pattern. However, I wanted to ask if anyone had found a source of hose parts in the club before I went down this potentially expensive route.
I'll take a look at eBay International and let you know how I get on.
Many Thanks.
Dave.
