Silicone hose I/D???

[Lowrcase]

I've just bought a silicone hose set for the radiator but it was only a 3 piece. Couldn't find a set with the 4th hose in the colour I wanted, the 1 that goes from the radiator cap to the expansion bottle. So my question is to people that have fitted silicone hoses, what is the internal diameter of said hose please?

Not 100% but pretty sure it's 10mm.

Just take it off and measure it. Make sure car is cold and disconnect hose end that by the radiator cup and keep it up to stop cooling leaking from expansion tank. 2mins to do

I replaced mine with an 8mm ID braided steel hose

Cheers guys! Love the braided hose but gotta be silicone for me but I'm guessing it's an 8mm I/D. I was hoping to get away with not measuring it as I can't till tomorrow & I'm impatient so wanted to order it today but I'll have to wait me thinks! There's also a breather that I need to do so I can fit an oil catch can!
