I need to go from a 7/8” hose fitting on my water pump into a 3/4” hose into my heater core. I cannot locate an adapter.

I have 3/4” connector. Should I just build up one side of it with something to make it fit? If so, what?

I must be missing something. Why does this need to be so difficult? It’s just a blankety blank water pump!
Thanks for your guidance.
