fuel pump whines

[eliasonb763]

I have noticed that on my 99 2500 crew cab, the fuel pump has started to whine VERY noticably. Has anyone else had this problem or am I just special?

Nah that happens. 97-99 seem to make high pitched noises that can be as loud as the exhaust.

does this mean Ill have to replace it soon? My pump went bad on my 95 and I personally replaced it, so it wont be that bad of a deal.

I changed mine at 38,000 on my 1998 Z71, bought a OEM pump module, and it whinned loud from day 1. I'm now at 88,000. Don't worry about it untill u are dead on the road.( I mean your truck, not you dead on the road).

How long has it been since you changed the fuel filter? Mine was whining pretty bad and after I changed the fuel filter it was quiet...

dont panic ive seen these last the life of the truck with a wine and ive seen the die very early, this is acommon gm problem if it does die DONT put a factory fuel pump in go with aftermarket pump with adjustable regulator in case you up grade your injector's or other mod's down the road ,,,,,,, good luck

GM doesn't make things like they used to. I have the original fuel pump at 284k and I frequently run it below 1/4 tank..
