hi i have a 88 sse with only 78,649 original miles and i just had to change my fuel pump due to a loud whistle. i took a doctors stethascope and went under the car. when i put it on a certain spot on the gas tank it really hurt my ear it was so loud.. so i changed my fuel pump and never had that problem again.. its been about 2000 miles since i changed my fuel pump and it has not made that whistle again.. my car only whistled when i had 3 quarters of a tank or less...
