Moroso electric water pump

Moroso used to offer different sized fitting that screwed into the pump body, I believe the ID were 1 1/4", 1 1/2 ", 1 3/4" and 2". I haven't seen any of those fitting in a number of years from Moroso. Meziere fittings may work I'm not really sure, you might contact them if you have the female NPT size.
