Diameter of fuel hose

Hi can anyone help with telling me diameter inner and outer of fuel hose from petcock to t_ piece. I want to lengthen it a touch to make getting tank on/off easy.

 

Long timer here TOE CUTTER did a fly by of chat about 1 1/2 hours after you posted your question and suggested this:
"TOE CUTTER: 95001-75008-60M BULK HOSE, FUEL (7.5X8000) (7.5X110) (BULK HOSE: 95001-75008-40M). My best guess."

I would place a lot of confidence in his opinion.

 

As you can see from image its bigger than 7mm
