there is a gasket between the pump and the motor. Did you clean the old gasket off completly, and did you remember to reinstall a new gasket? And also put some gasket material, I dont know high temp silcone or something, on both sides of the gasket before you put the pump back together. Other than that, make sure its torqued correctly, maybe try crossways like torqing a wheel. Does it leak from the pump itself, or where the pump meets the motor? If from the pump, replace the pump again. I dont know much else from here. good luck.
