Fuel Tank Hose

[Y194 ODX]

Hello everyone, Due to fuel smell I have to replace the hose between filler neck and fuel tank. Can someone please tell me the outside diameter of the petrol tank filler neck? I guess it must be something between 60 and 70mm. I'm having trouble measuring this as long as the hose is fitted between the petrol tank and the tank filler neck.

Many thanks in advance!

...should be 2,25 or 57mm...

I used the non reinforced version of this when I replaced mine (NH57NR):
