I may need to replace the fuel pump, testing it today. I see there are several brand options out there. I was leaning towards the Delphi as it has a lifetime warranty.

 

Is there one brand/part number which has proven itself? Mine is on it's 3rd pump and I'd prefer not to do this again!

 

***Seriously guys, telling me not to run my tank empty is NOT helpful.  I'm already aware off this fact.  Please only reply to this thread if you have knowledge or experience on which fuel pump brand is the best and most reliable for a 2000 Yukon.***

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

You have gotten many answers and struck them all down.  What fuel pump brand do you want to buy?   Delco or Delphi are the best OEM replacement brands that myself and anyone else here have good luck w

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.

I will not go with AC Delco pump as I'm currently on my 3rd one and they definitely did not last 150k each.  I only use Top Tier gas too.  So frustrating.

Are you running something that would require top Tear gas?

Just making sure you are not running high octane in a stock, unmodified engine.

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...

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

Whatever gives you the best warranty then.

 

I think this should be said here too. Yes the fuel tank should not be super low all the time but engineers are smart and so is the design of the modern fuel pump bucket.

 

The fuel pickup sock or point is on the very bottom of the tank, so it's going to pick up just about fuel left in the tank. Any fuel that is not used by the engine is either sent back through the return line right into the fuel bucket to keep the pump cool and supplied with fuel or it's taking a 180 degree turn after the feed on a returnless fuel system and sent right back into the bucket.

 

Low fuel levels can heat the pump up faster but it's still going to have fuel around it. Make it a habit of filling up when you have 5-6 gallons left, or just above the low fuel light.

Yeah dunno what to tell you.  Over 200000 miles and 15 years on my 05s original GM installed pump.  Surprised it hasn't rusted out and started leaking yet but it's good lol.  All I will use for stockish replacements is OEM.

Guys, I'm fully aware of the fact that I should not let the tank run empty. I have owned countless vehicles in my life and this is the only vehicle that has ever had to have a fuel pump replaced once let alone twice. There is an inherent design flaw with these pumps. 

 

Now, does anyone have any recommendations on which brand to choose so that I never have to do this again?

Nobody can guarantee you anything when all these parts are mass produced.

 

Either Dephi or Bosch is my vote because I can pick either of those up at a local Napa store.

I wasn't looking for a guarantee. I was looking for persons with knowledge on these fuel pumps who could point me in the right direction as far as the best brand for reliability and longevity.

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?

Starting in 04 all 5.3 & 6.0 had a returnless fuel pump these systems are known to last at least 150000 mi without replacement so check your vehicle to see if it has a returnable system, one indicator is no fuel filter on the frame rail it in the tank.

Top Tier (https://www.toptiergas.com/)has to do with gasoline quality, not octane level.  I use 87 octaine.

      I hope to high heaven this is wrong. My Chevy farm trucks frame is lasting way longer than a newer Nissan Titan XD I got for a steal, and it only pulls trailers. A decade younger and it's frame is already way rustier than the waxed Chevy I drive across longs and ditches. Also, hasn't Ford been having tones of troubles with rusted frames?

      Batteries don’t always show signs of a few years ago my vehicle started fine in the morning and took me to work. After work the battery was completely dead and I needed a jump. No, I didn’t leave anything on and the battery was only a couple months old. It was replaced under warranty.

      AFM is confirmed in the Corvette engine, so I'm assuming the higher volume trucks will get it as well

      If his battery was that bad I would think it would have been showing signs before this that were ignored. Stinks that it happened the way it did in rush hour traffic, but this seems like a pretty fringe scenario. I don't mind it that bad and never turn it off. The only slight annoyance for me is the slight delay between brake to gas, but I have gotten used to it and figure if it can save a little gas why not.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That is a good correction. I think “severity” was probably the wrong word for what I meant. What I really mean is closer to event priority, relevance, and actionability — not “this code is severe” or “replace this part.” I agree that a truck can have a lot of trivial or historical communication codes, and if the product starts pushing alerts for every stored or low-value event, people will ignore it very quickly. So the alert logic would need to be filtered. For example, I would not want a random old communication code to generate a push notification by itself. A useful alert would probably need to be based on things like: - new vs historical - active vs stored - repeated vs one-time - duration of the event - whether it happened near the driver-marked symptom - whether it happened together with voltage drop, reset, bus-off, misfire, oil-pressure change, etc. - whether the same pattern repeats under similar conditions So instead of saying “severity,” maybe the product should organize events by affected system and priority. For example: Misfire event: Show misfire counts / roughness first, then fuel trims, RPM/load, DFM/AFM state if available, coolant/oil temp, voltage, and related DTCs. Oil-pressure event: Show oil pressure first, but only in context — RPM, load, oil temperature, coolant temperature, DFM/AFM state if available, voltage, and baseline comparison. Communication event: Show which module/network/message dropped, whether voltage dropped, whether the recorder reset, whether it was active or historical, and whether it repeated. Voltage/reset event: Show battery voltage, crank/wake/sleep state, module reset, communication dropouts, and what came back online first. That also solves the display-order problem you mentioned. The main report should not always show the same fixed list first. It should show the system that appears abnormal first, and then the supporting values for that system. I also agree that the truck already has an oil pressure gauge and MIL. The point would not be to duplicate those. The value would be in showing what else was happening before and after the warning or symptom. For example, if the MIL comes on for a misfire, the truck already told the driver there is a problem. The useful part would be: - which cylinder or bank looked abnormal first - whether it happened after an AFM/DFM transition - whether fuel trims were already moving - whether oil pressure or voltage changed at the same time - whether the same pattern happened previously without a MIL On the OBD port point, I think you may be right for a consumer-facing version. OBD is much easier for the average owner: - easier install - easier removal - inside the cabin - easier phone connection - easier data download - easier to include a pass-through port for another scanner OBD is also the right place for DTCs, freeze frame, VIN, calibration information, Mode 6, and normal scan-tool parameters. The reason I was looking at ECM-side recording is that some events may be gone by the time someone plugs in a scanner, and some powertrain-side network evidence may not be available the same way through the DLC. But I agree that if an OBD-based version can capture enough useful evidence for most owners, that is probably the cleaner consumer product. Maybe the split is: - OBD/DLC version for most consumers - ECM-side version only if it proves it adds evidence that the OBD version cannot get - shop/pro version if deeper powertrain-side event evidence is actually useful So I would not want to force the inline approach if the OBD workflow solves most of the real-world problem. Your last point is probably the key product requirement: the report should be specific to the system showing the abnormality. Not “here are 50 parameters.” More like: “Misfire-related event detected. Here are the misfire/fuel/DFM/context values.” or “Oil-pressure-related event detected. Here is oil pressure compared with RPM/load/temp/baseline.” or “Communication event detected. Here is what dropped, when, and whether voltage/reset happened first.” That is a much better way to think about the report.
