Fuel pump noise
I recently purchase a 93 Eddie Bauer 5.0 Bronco with 90,000 miles. I have known the original owner and vehicle since it was new. It has never been abused and is in great condition. The seller did inform me of a loud fuel pump and told me that it has been that way since new, and that he was told by the dealer that this is normal. Still, it seems too loud to me. It is always noticable and frankly, it's quite irritating. Does anyone have any suggestions on how to quiet this pump down? I don't have any problems spending the money to buy a new pump, but I hate to go through the excercise to find that it hasn't gotten any better. Is there a solution, or should I just live with it and crank up the radio? Thanks for your help.

93, It's been my experience that all electric fuel pumps make noise, although they seem to get noiser before they fail. If this one sounds the same since new, I wouldn't worry about it. Pumps sound louder when in Broncos, hatchbacks, vans, etc. than they do in vehicles with a trunk that is over the pump and isolates noise. I would just turn up the stereo.

Other than cranking up the radio, does anyone have an idea? This Pump is really noisy. You can actually feel the vibration in the floorboards. Something's definately gotta get done. Any suggestions on a manufacturer for a replacement, or should I stick with Ford? Any other tips or tricks for quieting it down?

I've got a '93 too and have replaced the fuel pump 2-3 times since buying it new. Crappy system. But the noise I've never noticed, and certainly don't have rattling vibrations. Somethings wrong. Have it looked at as it's not easy to do; ya gotta drop the tank.

They all make noise nothing to worry about. Make sure your not hearing the smog pump. The fuel pump in my 95 went out I got it replaced no more buzzing. I guess its fine though. Lasted 7 years before it went out.

my 92 was the same was it vibrated really bad. I replaced it and it is much quieter. The new one still makes some noise, but not much.

Fuel pump noise
Hey guys this sounds just like the problem i'm having. About a week ago I started to hear a hum noise . I put a screw driver around to my ear to find it ,and it sounded like it was coming from the drivers floor board. Then I went under the truck and did the same to what looks like a fuel pump.( Is the fuel pump on a 88 under the drivers floor?) the sound was just like the one I heard inside. Kinda like a buzzing sound, but inside the cab It's like a hum? could this be it?

Fuel pump noise
[font size="1" color="#FF0000"]LAST EDITED ON 08-May-01 AT 08:42 PM (EST)[/font][p]I know you've heard it already but I had the same concern when I originally got the truck. The noise seems to be normal. After driving a few of my buddies trucks I've found two things about this problem, one is it seems to have no negative effects and two most of the fords I've driven have some degree fuel pump noise. As far as deadening the noise I got no suggestions. you could try building a cover but expect it will end up echoing. My bet would be look to sound proof from inside out. Maybe Dynomat, its probably more expensive than what you're looking for but it'll keep you from blowing your speakers. Good Luck.

If the noise is constant, then the filter, or regulator could be in a bind (or a kink in the fuel line). Change the fuel filter, and if you feel ambitious, change the regulator ($20 for stock, $50 for Crane adjustable). The trick on the regulator is to cut an allen wrench short, so you don't have to remove the entire fuel rail (you'll see when you get there).
Yes the noise is normal, but you should not be hearing it continuous. Another common problem is the tank's bung hole gasket wears thin, or the lock ring on the bung hole gets loose. You can feel for the lock ring, but the gasket change requires dropping the tank...then you might as well put a new pump in. Be advised, dropping the tank sucks, severely.

Personally, I get off on that pump noise. I turn the key on and wait for it to fill the lines so I can hear it...then start the beast up.
hope that helps.
