They fuel pump is running constantly with the key in the run position because there is something wrong with the fuel pump circuit, not because of a leak. The fuel pump only knows on and off. It doesn't care what the pressure is because that is taken care of by the design of the pump and the pressure regulator. nothin on that vehicle monitors fuel pressure and turns on the pump because it is low. If there was a leak that you can hear, than you would either smell it or hydroloc a cylinder if it was an injector leaking. I would start with the fuel pump relay. With an ohm meter you can check for continuity across the power side of the relay. It should be open when it is unplugged. If there is continuity then that is the problem.
