91 Bronco 5.8 Fuel Pump 'whine'

[VBsnow]

I have reviewed other threads on the fuel pump and they are excellent. So my question is:

I have a 91 that i have kept up for many years. I am about to hook a plow to it for the winter. I have noticed that my fuel pump appears to be a bit loud. However, it may have always been like this but I cannot remember. Basically, when you turn your key, you can hear the pump run for seconds and then cut off. When I start the truck, she starts right up. But when I am outside of the truck I can hear the fuel pump pretty well. It seems loud. Is this normal? Or is this a sign of impending failure?

Mine only gets loud when I get to around 1/4 tank of gas.. Once I fill it up it goes away and stays away until again, at a 1/4 tank.. and the less that's in there, the louder it gets!

20yrs almost with no issues yet!

well i can tell u that from the many fuel pumps ive done never heard one scream but thats not to say urs isnt goin to fail because sorry to say but whenever somethin is screamin on a truck it cant be good but hopefully nothin bad will come of it and its just another squeak that comes from an old truck goodluck buddy.

It is reassuring to hear that pump whine.. sorta like an AGT 1500 in an Abrams

Doesn't the pump/motor use the gasoline to help cool it? I try to refill before the tank reaches 1/4 full.
