fuel issues on 1994 Ford Mustang

just changed fuel pump on '89 mustang. when i go around a curve it dies??

Asked by for the 1994 Ford Mustang
How much fuel is in the tank try adding more fuel and see if the problem gets better. It sounds like fuel is sloshing away from the fuel pick up in the tank on turns. Could the pick up hose be loose or the pick up point changed when the pump was replaced?
