last couple of days ive noticed a whining noise coming from around the gas tank area.im assuming its the fuel pump.truck is under warranty but if it needs replacing i'd rather go with a performance pump.whats a good performance replacement for the stock fuel pump?i would need one that will still work as i do more and more mods. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

 

there are no high performance replacement fuel pumps yet. I got a walbro 255 LPH, but the pickup is different than stock, so I can't WOT with less than 1/8 tank or I lose fuel pressure.

Its extremely common.

If I was still under warranty, I would take it in and get it replaced. However, that wont guarantee the noise won't come back. Replacing without warranty at the dealership, you're looking at around 800 dollars.

Hope that helps some. I'm looking into replacing it in the near future as well, its gotten much louder over the years.

 

its not too loud.i didnt even notice it any last
night.i'll just ride and see if it gets worse.i hate taking my truck in to the dealer for anything.unfortunatly i've been in the car bussiness as a service writer for 11years and i know what can go on with cars while they are in for service.i can just see it...hey look he has a supercharger,lets take it out and see what it will do.... <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" /> ....CRASH!!!!!!i try to do most of the work myself with help from the techs at work.too bad we arent a gmc/chevy dealer <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />
