2008 MS3 upper Radiator hose inner diameter

[rednofive]

I'm adding an aftermarket water temp gauge and would like to use something like this for the water temp sender:

I'm looking for the correct stock upper rad hose inner diameter for ordering the right part.

If one of you already knows this and will share it, it'd be really appreciated.

thanks,
