Man, sorry that no one has posted up to help you! I myself have'nt experienced this. I don't believe it should make any noise at all, even if its going out. I think its something else?
When mech. fuel pumps go out, you can tell by the safeguard they put in it. They've got a hole in it so it will leak gas when the diaphragm goes out.
