defender 200tdi top hose ID

My 90 has a disco 200tdi engine in and i remember using the top rad hose from the 200tdi disco i pulled apart for the engine, Does anyone know the internal diameter of the top rad hose as i can't find it anywhere on the net...

I read one thread where the guy had used some 38mm ID hose instead but I could do with knowing the ID without having to measure it tomorrow

I would say either 32 or 38 maybe look on ebay at the elec hose mounted fan switches and see what size hose they list?
May also be a silicone custom made hose for your car as there must be way way more tdi converted 90/110 than there ever were oe tdi models?

First one I found http://www.ebay.co.uk/itm/LAND-ROVE..._Clothing_Protection&var=&hash=item33982d46d4

Tried ebay there were several diff sizes. Ordered a 36 and I'll see when it gets here
