The main fuel pump can be noisy if it does not get enough fuel, mostly if the in-tank fuel pump is not working. For example if your gas tank is pretty full, you most likely do not hear any noise since the weight/pressure of a full gas tank is providing more pressure for the main fuel pump which is mounted underneath the car in a subframe. So if your main fuel pump is getting noisy with an almost empty gas tank it's most likely the in-tank fuel pump that is not working. Also check the corresponding relay (usually white) underneath the passenger glove compartment. Bottom line, If your fuel is pump noisy, but you are still driving, your main pump most likely is still good while the in-tank pump is not working.
