    :frown1: How can Chevy not stand behind their fuel pumps???? They obviously have a problem. Every newer Chevy that I or any of my friends own has lost the fuel pump at just over 50k miles. I was talking to my buddies at the local parts store and they say that they sell 2-3 new fuel pumps EVERY WEEK....and we live in a small town. Has Chevy fixed this problem now that they are extending the factory warranty....I'm sure they have, now that is will be costing THEM money. What are your thoughts

    ?

    that happened to my grandmothers suburban at about 93,000 miles. i to live in a small town and they say they have to fix at least 3 every other week. my grandmother just recently bought a new suburban. the guy that she talked to on the phone says that they have made some changes so it doesnt lose pressure. what they did though idk, but thats been the only problem we have had on our newer chevy's. other than that they have been fine.

    What's crazy is that it is a fairly easy fix, just a pain getting the tank out, and the shops want $1000-$1500 to fix it. The part is only $300 and it took a buddy and me about 3 hours to do the last one. Wow, that's some shop markup.

    It's not just chevy, Dodge has some real ****ty pumps too! At least it's cheap if you do the work yourself.

    guys..pumps are dying early because they aren't getting lubed by the fuel anymore. the EPA reduced the sulfur content in gasoline starting last june, and sulfur acts as a lubricant in fuel. ( just like a diesel ). furthermore, ethanol , which is being used as an oxygenate, contains alcohol which reduces a fuels lubricating qualities even further..

    warranties don't cover parts that die from lack of lubrication, they only cover materials and workmanship.. since gm doesn't make your fuel, well, you know..

    her's my $.02, I am a mechanic, and from what I have seen, on alot of these newer trucks, when the pump goes, which is fairly often, the fuel filter is either original, or hasn't been changed in quite some time, also the gas in the tank cools the pump, so all these trucks running on 1/4 tank or less are killing there pumps. I personally would change the fuel filter every 12k, and when you do, take it off and shake it and pour it out the inlet side, and watch the mud flow. now i'm not saying that chevy's don't have a problem, but this aids in the pump failure.

    sounds good, but Chevy fuel pumps have been a fairly known problem for a lot longer than since "last june".

    x2. this is a very common problem for quite a long time.. its not alwasy the fuel.

    The point about the pump getting too hot is quite possible though...

    I could see that as a possible issue. I don't really worry about it. I've never had a pump go bad on one of my trucks (knock on wood), but they aren't that big of a pain in the ass to change if I have to.

    I guess I've been fortunate--my '01 HD has 113K and no pump problem yet, but i do change the fuel filter regularly and try not to go below 1/4 tank. Does anyone know when the recall was issued or any other details?

    hell I know when it is time to fill my truck when I jump on it and it bogs. I run that thing so dry EVERY tank, that if that was the killer of fuel pumps, I'd have gone through a hundred by now. I coasted in 2 tanks ago, literally didn't want to maintain idle anymore. Haven't changed the fuel filter in over 30k miles(siezed in place, have to custom fix that...)













    knock on wood...

    I'll also vote for this one!

    I always fill up when I get gas and my pump has over 225,000 miles on it....

    Did I just jinx myself?:eek1: *knocking on wood*

    Of the family member vehicles that I know of (about 5 or 6 'newer' full size chevys) they haven't needed pumps in their 200,000 mile lifespan.

    On the other hand, my buddy who only puts 1/4 tank in at a time, well... he's changed a few pumps.


    Take it for what it's worth. Just one guys experience added to the story...

    all manufacturers say the killer of pumps is running them on empty all the time(heat and lubrication factors), I've been lucky most likely, but I'll continue to be until I need a pump, haha.

    The National Highway Traffic Safety Administration is ordering the recall of 38,439 General Motors SUVs and pickups because of a potential fuel leak that could result in an engine compartment fire.
    GM is recalling the 2004 Chevrolet Avalanche, 2004-2006 Chevrolet Avalanche 1500, 2006 Chevrolet Kodiak, 2004-2006 Chevrolet Silverado, 2004-2005 Chevrolet Suburban, 2006 Chevrolet Suburban 1500, 2004-2006 GMC Sierra, 2006 GMC Topkick 6500, and 2004-2006 GMC Yukon XL.
    NHTSA reports that some of the GM trucks equipped with the 8.1 liter V8 contain a fuel rail pulse damper retainer clip that can fracture resulting in a fuel leak which is near an ignition source in the engine compartment.
    Dealers will replace the fuel rail damper free of charge when the recall begins. Owners may contact 1-800-630-2438 and GMC Trucks 1-866-996-9463.
