Lower water rail hoses

[lanciamad]

Anyone know the inside diameter of the two hoses next to each other on the lower water rail nearest the o/s I haven't looked for ages, I believe one goes to the throttle body not sure about the other without looking.
I don't particularly want to drain the system/lose coolant just to check the size with these current temperatures

One is 16mm and goes to the heater matrix and the other is 8mm and goes to the auto choke.

Brill, thanks for that targa2000
Hose bought, just some hose clips to get and I can make a start on replacing the whole coolant system
