Strange sound

[Petewes2]

I have a 91 sho and recently had a fuel pump replaced. After the pump was replaced it seemed the car was running very loud. It hAs now been about 3 weeks and this noise has gotten louder and more pronounce. This noice is most prominent in speeds 30-50 mph. The noise is a very deep sound and sounds no differnt what gear you are in. If anyone has any idea what this could be please let me know. Thanks.

does it do it while driving or at idle? Its probably a wheel bearing.

some pumps are noisy. try running the pump with the car shut off.

It does while driving even in neutral..the rpms have no influence on it

Electric fuel pumps run at a constant speed, except some of the earlier SHos that had hi and low. I forget which ones.
