That's good news: You can pickup a standard 3/4 fitting (socket to thread adapter), and it will fit nicely over the 1 inch OD pump intake. You can then screw in a 3/4 to 1/2 reducer, to screw in a 1/2 barb. It's a good configuration.
As for the pump outlet, a 1/2 fitting should fit over a 3/4 OD, in the same fashion as above.
You'll have to use a good glue (and Goop to seal it all, if necessary). The glue is going to be hard to choose, especially if your pump housing is glass-filled polypropylene...
