Well, after drivin to the dragstrip which is about an hour away , and i do some rough driving to get there , my fuel pump will begin to whine. It's pretty annoying and even letting the car rest for about 45 min, it still is noisey. I do not think the amount of gas mattered in these situations because it does it no matter how full or empty. Mabye its just a GM thing, because my parents suburban does it too... hm?

My stock pump made a loud hissing noise on long, extended drives in hot weather. The GM full size SUV's seem to suffer from bad fuel pumps as much as the 99-05 Grand Ams. It seems if you run with low fuel (next to E) even once, it damages the pump pernamently.

My camaro pump whined like a little bitch. Pulled the pump and the sock from the bottom of the pump assembly was almost completely plugged, cleaned and solved the problem. Usually when a pump whines it is a restriction or it is about to completely die on ya....

My car made a very loud whine everytime I drove it over about an hour straight when it was my daily driver (years ago). It stopped making the noise cause I never really drive it for more than an hour straight anymore. The pump still worked fine for another 2+ years until I replaced it this past weekend. I had plenty of dyno runs and fuel pressure was fine. The only reason I ended up replacing it was because I didnt want to have to worry about the stock fuel pump and having a cam/bolt on car + a wet shot.
