GMC Safari Fuel pump vibrating loudly

i have a 1996 GMC Safari i changed fuel pump in the tank it worked fine for about 10 miles then it just died while going 30 mph and a loud vibrating sound came from the tank and car wouldnt start and everytime i turned the key forward that same loud vibrating sound happens.

So i thought it was a bad pump so i replaced it again and the same thing happend but this time i made it home and when i went out the next morning i tried to start it and the same loud vibrating from the gas tank.Not sure what to do next before i try to change the pump yet again.
