I'm afraid it's bite the bullet and buy the 3 piece set (this is only how it comes, as i found out in your situation) or, go to Halfrauds and try for a bendy universal bit of hose.
How did you find that out ?Hi guys after som searching i found that a cut down triumph 2000 hose has exactly the same bore and curves as the rad to T piece hose..... cost me less than a fiver off ebay
