So what upper hose are people using with their Champion Radiators that show the upper being 1.75" ??

Re: Radiator inlet and outlet diameters?

I fabricated a 1.5 hard line upper hose and used a 1.75 to 1.5 reducer at the radiator, but it would probably be just as easy to use a rubber hose with a short piece of 1.5 hard tube as a transition between the rubber hose and the reducer.
