In this video I replace the fuel pump module in my 2005 GMC Envoy. For a few years now I've been having issues with the fuel gauge not reading correctly or at all. I knew what the issue was and how to fix it but because it is such a big and not so fun job I put it off as long as possible. I've had to count my mileage to know when the tank was about empty so that got old quick! Finally, I had the time and determination to fix it. With this vehicle (and a lot of others) the fuel pump 'module' also contains the fuel level sensor and so when the fuel level sensor goes bad you pretty much need to change the whole thing altogether. That's okay though since because I was dropping the fuel tank I might as well get it all taken care of at the same time anyway. So, by fixing the fuel level sensor I also have a brand new fuel pump.

Take it from a technician with more than 30 years experience. Never ever use a Shop-Vac to vacuum the dirt off of the sending unit or anything else on the fuel tank! Fuel Vapor gets sucked into the vacuum and the electric motor inside the vacuum can ignite the fuel vapor in the vacuum, then you have a problem. Use a plastic brush and scrub it if you have to and blow it off with compressed air. If you're working in a home garage and have a gas-fired water heater in the garage like some homes do shut the gas off to it make sure there's no pilot light, fuel Vapor will accumulate in an enclosed space soon as you open the tank.

One thing I've learned when it comes to getting fuel pumps nowadays is to never give them your old assembly as a core if they want it until your absolutely positive that you are happy with your new one. Also it's extremely hard to find quality parts nowadays, I always try to stick with oem parts especially with fuel pumps but it really depends on what I'm working on. A lot of times I'll get complaints with new fuel pumps that the gauge isn't working properly like theres still tons of fuel left when it reads empty is common or it's really noisy and doing weird things etc.. a lot of the time what I do if I have to get a new aftermarket pump I will try to reuse as many original parts as possible from the old one like the sending unit for the gauge if it was working. Also what I've done when the oem isn't available I'll take the old pump assembly apart and try to get a part number and information off the pump itself to get through the pump manufacturer like Bosch, walbro etc.. most everything you get at the normal parts stores is just junk, it either doesn't work right or fails quickly. It's gotten really bad.

Good mention on NOT vacuuming gas fumes. I can only imagine the sparking of vac electric motor, fast moving air gas mix would GUARANTEE a firey situation.

Jimmy you are the reason I keep my older vehicles on the road rather than trade them in at 200, 000 miles like I used to. I own a 2003 and 2005. I was inspired when you said that you just keep driving that old suburban from the 1990's and keep on top of any issues at all times. Keep up the good work buddy!

[ChrisTheBmxGuy]

Also a tip, they make fuel pump retainer ring tools that have locking teeth that grab into those slots you used a punch on. Just put the tool on a long breaker bar or big 1/2" ratchet and giver a yank and it pops right off. Now I understand its not a necessity if you hardly ever need to take a pump out but I use it a lot at work for diesel def and fuel pumps.

Worked for a government fleet and had to replace 18 in tank fuel pumps in 6 weeks.
A month earlier we had received our winter gas, no ethanol, 3 vehicles, all police units lost 2 pumps each. All were 2014 and newer, Dodge, and Fords.
Tanks were cleaned and inspected before installing the new pumps.
I noticed the gas was an odd color so I called our supplier, who called the refinery, nothing was ever admitted to be wrong but a few days later the supplier pumped out our 3 in ground tanks and dumped 2, 800 gallons in, no charge. No more failures either.

I fixed a bad sending unit in my Chevy Equinox by filling the tank to 3/4 full, putting in a can of gas cleaner, then driving for an hour over a bumpy, unpaved road. The constant bumping jiggled the sending unit, and combined with the cleaner, this dislodged the crud that was messing up the sender. May not always work but worth a try.

I've done this a few times since the 90s but it's great your doing this for others, way to go.

[chashamton]

Best rule of thumb 👍 once your at a quarter tank consider it on empty that's what causes the arching and over heating of the pump.

Back in 2011 when I replaced the 2.2 L engine in my 2000 S10 I also replaced the fuel pump. Very similar procedure to your Envoy. I replaced it with a Carter fuel pump (Made in USA) only to have it leak in a few years. I then replaced it with a Spectra Premium fuel pump (imported, I forget where it was made) only to have the fuel gauge fail in a few years not to mention a persistent check engine light due to a less than perfect vapor seal. I finally “bit the bullet“ and purchased an “original equipment“ AC Delco fuel pump that believe it or not was made in Malaysia. No problems so far.

In case anyone is wondering, or needs to replace their fuel pump in the future on any GMT-360/370 models. If an AC Delco Fuel Pump is not available, use a BOSCH one. They essentially were the provider of the AC Delco branded ones, its been observed over the last few years on various forums that the AC Delco pumps will have a BOSCH part/serial/model number listed on the unit, and they're a fair bit cheaper as well.

I still don’t get why every video has “WHY I NEVER MESS WITH THE FACTORY -“ but then no explanation.

My wife and me were walking down a street when we saw 3 or 4 guys pulling out the gas tank from under a pickup truck. They said they were replacing the fuel pump again. He said that was the 3rd brand new fuel pump he has replaced in the past 2 months. I asked him if those new fuel pumps were aftermarket from the local parts store and he said yes. I told him that I've heard aftermarket fuel pump never work very long and it would be better to spent more to buy the OEM fuel pump. That way you will save a lot of time and effort replacing the fuel pump every month.

One *very* important thing you didn't address was the recommendation of replacing the fuel filter. Some suggest doing so every 5 years / 50, 000 miles and others may say every 20, 000 - 30, 000 miles.
Clogged fuel filters can cause:
• Poor Engine Performance
(Under heavy or high-speed acceleration, a clogged fuel filter may cause the engine to randomly hesitate, surge or sputter)
• Hard Starting
• Stalling
• Random Misfire or Rough Idle

I recently changed the fuel filter on my '93 Grand Cherokee and as I poured the residual fuel out of the filter itself - a *lot* of what looked like black 'silt' came out with it. Definitely was WAY overdue and am now worried there's plenty more where that came from, left in the tank itself.

A huge amount of respect to you for tackling this large gas tank... on your back! They're difficult at times, even in a fully-equipped shop with a lift AND a tall transmission jack!

I see the scratches on your hands, I also always get wounded especially when it comes to hose connections and handling fuel tanks with gas or fuel still in the tank . Gas sloshing around sure makes removal very difficult . Great video .

[AreaThirteenThirteen]

I miss the good old days when the fuel pump was mounted on the engine block vs inside the fuel tank.

[MrBowNaxe]

Good stuff Jimmy! Unfortunately I've done that job on both my Suburbans... That looked easy compared to getting those 42 gallon steel tanks out from under a Suburban. Thanks for sharing.

[troydorr]

I gotta say, I share the same enthusiasm when I work on my own car. The hardest thing I've done, was putting a new turbo in a 2008 VW GTI. And anyone with a Volkswagen knows how difficult it actually is to remove and install. They recommended pulling over sliding the motor forward. But I did it without moving it. Pretty time consuming, but rewarding.

[verohandymike]

On some vehicles you'll be lucky and the manufacturer has chosen to put an access panel to the gas pump, usually under the back seat or inside the trunk. Turns a pump replacement job from several hours to about 1/2 hour at the most as you don't need to remove the tank.

Awesome video! I just did mine on my 2001 tahoe. Also drained tank and cleaned it with dish soap, lots of water, and dried it. Works awesome... it's a 6.0L tahoe I am building. Next thing is to upgrade to flex fuel injectors I have on my bench. Pretty cool project. Love your videos!
