Weird sound coming from my 5.0

[Waz900]

Anybody with a Fox, eyeball this one. I have a 92 5.0, and I am hearing this werid buzzing/whining sound coming from the back of my mustang. It is coming from the back of the car, behind the right tire. I think it might be the fuel pump. It sounds like it doesn't want to shut off or something. As soon as I start the car, you can hear it, and its annoying. I can't recall if it was always there and I just noticed it now, or if it has been there since I bought the car. Anyone have any experience with this noise? And does anyone know if it is harmful or just a noise that just happens with these cars? Thanks!

Fuel pumps on Foxes are normally pretty noisy. Might be normal. I can only hear mine when the key is turned to the on position but the car isnt running.

do you hear it when you turn the key to 'on' but dont actually start the car? the FP will prime for a couple seconds.

they are noisy, and in my experience, noisier when the tank is getting low on petrol.

good luck.

Mine was pretty loud - you can hear inside the car, and standing behind the car. Lift up the carpet and listen to the right of where the spare tire sits with the car running - the pumps right below there. I switched mine out to an aftermarket pump, and was much quieter. Folks often say a loud pump is getting ready to take a dump - dont' know if that's for real, or just an "old stanger's tale".

I am from the U.S., but i have been lucky enough to see a few places. That was a throw-back to a little time spent in New Zealand.

In my experiences, I've found that fox body fuel pumps get louder with age, and start to sound like a dying cow when they are ready to quit

In regards to the fuel pump noise when they are going bad, I've heard this expression:

"First they talk, then they squawk, then you walk..."
