Coolant Hose ID

Can anyone confirm what the INTERNAL and EXTERNAL DIAMETER of the bottom coolant hose is (preferably in MM rather than INCH).

This is the short hose which goes between the front of the water pump and the bottom of the radiator.

Help appreciated as ever.

1.25" / 32mm inside measurement - measured from an old OEM hose.

I used a (1) Goodyear # 61028 which provided both hoses (if cut correctly). Other off-the-shelf hoses could work as well, provided the bend is correct.

Thank you Scotch,

Like you, I have used regular everyday coolant hoses for the 1300 in the past, but just wanted to know the sizes before I remove them, so I can order and have new ones with clamps ready to replace.
Really appreciate your help.
