If there was some kind of "inherent design flaw", there would be WAY more posts about replacing fuel pumps.  I replaced my fuel pumps (I have 2 tanks) 4 years ago, haven't had a problem with them since and I've put on 100k km since then. I think my main, important pump (the one in the front tank, pumping to the engine) is an Airtex, but my system is also a returnless style, so it's different from yours.

 

I would say it's more likely that there is some specific problem with your truck, such as it generates too much vacuum in the tank, or an electrical problem, or the pump has to work to hard because the FPR is faulty, or maybe something else.

 

And is this 3 pumps since 2000, or your 3rd pump in say, 5 years?

Seriously?  There are 100s of posts about GM truck fuel pumps spanning 2 decades.  It's a well known problem.  I just couldn't find a post referencing replacement brands.  Go to YouTube and look at just how many "How to replace fuel pump" videos there are for GM trucks.  Far more than any other vehicle on the road.

 

My truck is a 2000 with 217k and it is currently on it's 3rd fuel pump and possibly looking to see its 4th.

Delphi is good quality. Sometimes they outsource but the outsourced part is of similar quality.

Just go AC Delco OEM and expect to get about 150k miles out of it. It is a 45 minute job with a $125.00 part of not that much invested in the project.

How empty do you run the tank?  Have you run out of gas?  Fuel pumps will die very quickly if they run without fuel going through them...

Fully aware of all of this.  Looking for experience and knowledge on the best brand for replacement.

Don't let your truck get below 1/4 tank. The pump needs the gas around it to cool it.

Fully aware of all of this.  I'm looking for experience and knowledge on the best brand for a replacement pump on a 2000 GMC.

Delphi since you don't want AC Delco anymore. I tend to stay away from Bosch products

That's Funny because the last inline Delphi pump I bought was a reboxed Walbro pump. Walbro makes great pumps.

Negative...If you read all of my replies, I have not struck down a single brand suggestion with the exception of AC Delco because they were the pumps which have all failed me.  

 

The only people I hit back on were the completely unhelpful comments telling me to not let me tank run dry. Cool...Super...That doesn't help me choose a new fuel pump.

There are millions of these GMT800 trucks in service.  Of course there's going to be hundreds of how to change the fuel pump videos.  If the fuel pump system had some kind of inherent flaw, than there would be WAY more videos and complaints about having to change the fuel pumps over and over again.  There aren't.  It is much more likely that there is something specific to your specific truck, or how you drive, or fuel you put through it, that is somehow causing your pumps to fail every five years.

Definitely leaning towards Delphi, thanks for chiming in.  I like the fact they offer a lifetime warranty too.

I don't know what else to tell you except talk to any die hard GM truck person and they'll tell you about these fuel pump issues.  You're just being a troll at this point.

It looks like the Walbro pumps would require a decent amount of modification to make them work in my 2000 Yukon (in tank fuel pump).  They don't have line in/line out and I don't beleive they have a built in float for my fuel guage.  That is in addition to wiring a custom electrical harness or adapters.  I much appreciate the suggestion and chime in though.  I should have emphasized "plug n' play".

If you live anywhere near the Washington, DC metro area, I will pay you local dealership rate of $165 per hr x 0.75 hr labor to come knock this out for me! ?

Well, there's a difference between needing to replace the fuel pump, and needing to replace the fuel pump every couple of years.  There are way too many people running these trucks and holding onto them until they die, that would be posting left right and center about having to replace their fuel pumps every couple of years.  Except they aren't.

The original pumps were not holding up, and you did hear about them, but by 2004, 2005 or so, those issues had pretty much gone away. The replacement units were better built. When we had nothing but GMT800s in our fleet, we replaced some pumps, not every one of them failed early though, we put a lot of miles on 'em. Double check all your electrical. Poor connections can cause issues and premature failure. Your system is a fuel return system, make sure it is operating correctly and allowing fuel back to the tank.

 

I will say I'm rockin' an AC Delco that was replaced under warranty. That's been over 100k and 12 years ago

In 2004 GM introduced the returnless fuel system, it lowered vapor emissions mandated by the EPA. Returnless systems improved fuel pumps and eliminated return line and external fuel filter, this cooled down the fuel due to constant recycling of fuel. Its not unheard of for pumps to last 150000+ miles. AC Delco and Delphi are one in the same.

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
