Upper radiator hose size

Can anyone help us out with the size of the upper radiator hose. I need to buy a Greddy adaptor for a gauge sensor and I haven't got a clue which size to get it in mm.

 

Cheers

    It's 38mm inner diameter all the way through fella, you can source tee offs that can be cut into the top rad pipe on cars, bit fiddly on ours because of the short length and shape, but possible, you can see em in demon tweeks, however fitting yer sender is a different matter, hence why i do the top ones in stainless and boss to suit any gauge,

    Cheers Paul ... I measured the pipe itself and guessed that I would need 38mm

     

    I will fit the adapter for now and later get you to make me up a proper boss with your rad kit ....
