If it were me I would get a barbed npt brass fitting and replace it. The rest of this unit is CTO its for switching vacume based on coolant temp, flap valves in air cleaner snorkle and such things. Follow the gob of vacume lines that hook to it and see if you can live without those accessories. You have to source a used one, I didn't find anything on RockAuto.
