ID/size of coolant hose from radiator to engine

[Dweeb]

Hi all,
My TAM is in storage long way from where I am, so I am asking for some help/information. Does anyone know what the ID (inner diameter) is of the coolant hose that goes from the radiator to the engine ? I want to insert a electric inline water pump, I would like to order it now so i have it before i get my TAM back from storage.

so, what's the ID of the coolant hose ID between the radiator and the engine:

Also any recommendations on the electric water pump ?

thanks
