Fuel pump doesn't stop priming.

When the key is on the "on" position the pump primes like normal, but when the car is idling, or I'm driving the fuel pump constantly sounds like it is running, and releasing a loud humming noise, that's even easy to hear from the drivers seat. Anyone know what it could be before the fuel pump, filter, and strainer get replaced? Its a 1991 camaro, forgot to add that.

Fuel pump is supposed to be running continuously with KOER. Noise may be indicator that the pump is on the way out.
