1987 Ford Bronco V8 Four Wheel Drive Automatic

Just replaced the tank pump (old one was shot) Before replacement, the pressure was about 50 psi for the few minutes it would run before quitting. With new tank pump, the rail pressure is now 80psi. This seems a bit high to me. Anybody know what the correct pressure should be??
