What are the ID of the fuel tank return hoses?

I can't remember for sure - sorry - but I have a sneaky feeling 8 (mm) is the magic number

I hope someone else can help

6.5 and 8? just measured

Although petrol based information, the information here =>

Fuel Hose Selection, Pipe Grading (Why R9), Connections &amp Clipping

About fitment of fuel pipe towards the bottom of the page is important to note
