fuel pump

i have a 99 chevy silverado 95,000 miles on it,noticed the fuel pump starting to make the winning noise,had the brand new gas filter so i put it on ,,its not that loud but loud enough you can hear it ,,, you guys think it time for a new one or will it last a while, a friend told me he put a new one on his truck and it was still loud. what you guys think,,,, :evillol:

if it it still does its job then don't replace it

I've got a 2000 and I noticed it started whining a few days ago. I poured some seafoam into the tank about a month back and I don't think that would cause the whine. It seems to have gotten a bit louder although maybe its just me...I hope it's not getting ready to die on me...Could there be moisture in the tank or anything besides a dying pump? Any suggestions?

must be something with GM pumps my gf has a 98 malibu and it does the same thing

OK I DONT KNOW IF THIS IS WHAT FIXED IT BUT FUEL PUMP STOPED WINNING,LIKE I SAID I HAD THE FUEL FILTER ALLREADY BEFORE THIS PROBLEM,ONE DAY IT STARTED WITH WINNING SOUND SO I PUT THE FUEL FILTER ON,DROVE IT SOME THAT DAY WITH IT WINNING ,WELL THIS MORNNING THERE NO MORE NOISE AND IVE BEEN DRIVING IT ALL DAY , ANY WAYS HOPE IT DONT COME BACK :evillol:

airjam , what is seafoam and what does it do? i have never heard of it.

seafoam is pretty much the same thing as B12 Chemtool..its some sort of fuel injector cleaner..it also removes moisture form fuel and oil....it helps remove varnish from lifters and breaks up the gumming up on piston rings....i used it not too long ago and definitely noticed a bit of a difference at idle....the motor seemed to run a bit smoother and get there quicker instead of running rough for about a minute....When the whining started on my fuel pump it was the first warm day here in dallas in a while...hopefully it was only some moisture in the tank and nothing serious with the pump.....i guess we'll find out soon enough..

Was it especially cold out when it was whining?

I noticed mine whines when its cold. We're talking in the 40s. Only does it when its that cold.

I thought I had an issue with mine (turned out to be a dirty throttle body) and called the dealer. Diag cost they quoted me was only $85. Thats a lot easier to swallow than $480 parts/labor for a new pump.

If you really think the pumps bad, is $85 worth peace of mind?

yeah my pump whines all the time... well it did this winter... but it was -30 and -40 C and now that it's startng to warm up it's kinda goin quiet on me... but there is a place that sells rebuild kits i've found on here... 700$ for a new pump for my 2000 s/b vs. 85$ for a rebuild kit... go figure :) i've got buddy's number if you want it...
