I think i'm right in saying that there's not much size difference between the 2. So I guess either would be ok.

Needless to say I will be doing mine in millimeters , and will probably use some fuel line hose that's stiff enough to hold its own shape. for my bypass tube.

I guess the internal diameter needs to be a large enough to be effective but not so large as to divert to much flow from the radiators when the coolant is super hot.

Perhaps a small inline tap could be fitted in to the bypass tube to control flow .
