Does the truck seem to run right other than the noise?
And did you change the fuel filter as well. You should always change the fuel filter when you change the pump since there's a good chance that it's what caused the pump to pack it in (they get clogged)
The only other thing to look at is the fuel pressure.

Fuel pump is normal when it's whining. Some fuel pumps Whine louder then others.
