A new seal apparently fixed everything. I don’t know if the pump was replaced or what. I’m starting to irritated with shorts.

And here I thought you were going to show the fuel gauge a final time, showing the difference.

Problems not always in the fuel tank or on the fuel pump sometimes it can be behind the dash

Everything is so new and clean and easy to work on

I’ve never ever saw a tank etc so clean! We’re do you drive it? Indoors😂

If you go to all the trouble of dropping the tank, might as well replace the whole pump to ensure you don't have to drop it again for a good long while.

Here in the northeast you'll need new hardware, fuel tank straps and probably a couple of the lines off of the pump. That vehicle is brand new or this guy is in southern CALIFORNIA

Noticed he use a brass bar to drive the ring in place, because brass does not spark.

Turns out my car just needed more gas and not just $10 every two days

When will you enlighten us on how you fixed anything?

Just remember to fill up when the gas gauge hits a quarter tank and you won't have to go through this needless repair.

Br0,Your gonna have a whole new truck when it’s all said and done! Great channel! Keep it coming

A bottle of Chevron's Techron complete fuel system cleaner at every oil change helps this issue too. Chevron IS the same as GM's fuel additive.

Just did a 62 gallon replacement tank, and did the sender twice because the first one was faulty. That was a pain in the butt.

Do not use an electric vacuum around a fuel tank. Fumes and electric motors don’t mix!! Brake clean and compressed air. Unless your looking to blow your house up. 😮 you used a brass punch for no sparks but used an electric motor.

You ever seen a more pristine server come out of a vehicle looks factory new

Make a pump access door! I did last month and love it!

If you never let the guage drop below 1/4 tank you'll never have this problem. The fuel cools the pump.

That Trailvoy looks brand new under there. We don't get that in New England. I just replaced a fuel pump on a Trailblazer because the vent line was rusted through and wouldn't pass emissions test. Rust is REAL up here!

Thought it was ethanol thing at first.

So if I see that the brushes are dirty I can just put it back together and it’ll work?

Easy job when it looks like new!! compared to rust buckets!!

Great now Every customer that comes into my shop is gonna think it takes two minutes to do a fuel pump. Thanks a lot jeesh 🤦🏻‍♂️ 🤣🤣🤣🤣 Btw no way that things from the north east cuz we NEVER see them that clean 😫

That's an awful clean trailblazer/envoy. The majority of them are rusting and leaking everywhere

I know my fuel gauge is wrong. I have a 16 gallon tank but by the time my needle hits "E" i have between 4-6 gallons left.

If you were in Wisconsin, you would be replacing the tank, too. Stupid steel lock ring mount rots right out of the tank from all the salt and junk sitting on it. Dodge had it better in the early nineties already with a plastic threaded ring.

Would be nice if you would measure fuel flow before dropping the fuel tank and removing the fuel pump

He shows the new fuel pump with the new sending unit attached to it In the beginning. When a new fuel pump housing is purchased it all comes assembled. So he replaced both like he stated.

How he tightened the fuel pump I assume he took it off the same way! Good jewel dropped there

Wow that’s pump is clean I’m use to seeing the top rusted out causing evap leaks and fuel leaks! Also see several that have to replace tank due to cam lock retainers rusted off! Job much easier without rust😂

Ur gonna want that tank empty and be outside. The fumes are very strong when the pump is out

Always let your car prime the system before trying to start. Like, really really prime it correctly. Don't ask me why, I just hate doing spider injectors.

Add a heavy dose of Lucas fuel treatment to break in the new fuel pump, it will run quiet and smooth you'll get longer life out of your fuel pump

It's almost easier to jack the bed up. I did my s10 that way on the side of the road .

you didn't fix it you just replaced it

I love how easy that is I think I'll do it tomorrow after work and be at work in the morning

Only thing bad was the brush so clean the damn brush!!!!!!!!!!

I'd be cursing the engineers.

That's funny a couple years ago I had to do my 2010 Mustang fuel pump and then this summer I did my 1959 Ford Thunderbird fuel pump and my 2004 Chevy Silverado fuel pump. I'm considering myself pretty much an expert now.

It's easier to remove the box.

Not good to use a shop vacuum to remove debris from tonk top if there is gas fumes will get in the vacuum and cause an explosion !!!

Upload a video putting a 12450086 lamp 💡 underhood in a 2004 Envoy with 25751099 harness underhood ??

Wow…was the gasket not grounded or what?

Usually simpler to tilt bed up

Now I need a video that shows how to stop vapor lock I drove this Dodge van around for five six years it ran like a charm. And now it when it's hot outside it will stop running or won't start at all but you come back in the morning when it's cool and it starts right up

The outtakes are great Paul. You should add those in more often. 😂 when one of the students responded you want me to go into a class I'm not in, and ask what they are doing? As a student, I'm not even a teacher. 😂 killed me.

People, here is a video that shows you nothing of how to fix a incorrect fuel gage or pump. But we all learned how to install a new gasket.

Notice that he is using brass to put the ring back on. It 0nly tales one spark to blow yourself up.

Lifting the bed is way easier !! Especially if there’s more than a 1/4 tank of fuel

The cluster needs to be fixed 100%

Those contacts as well as the plug connector outside the tank are notoriously known causes for bad fuel level readings and the fuel pump itself not working.. I have seen many people replace their fuel pump because of a bad connection as well.. GM really caused a bunch of unnecessary problems with those horrible designed connectors all over their vehicles.. I worked at a Chevy dealer and if the average person only knew all the bulletins and causes of reoccurring problems for the same failures and complaints they probably wouldn’t believe that any company would be allowed to get away with what they do.. I used to really enjoy auto repair because I really felt good about being able to help people.. I know how much we all depend on our vehicles and spend our hard earned money in good faith that with the premium we pay for vehicles, we would be getting our money’s worth.. Not so much as it turns out.. Dealers have all of the factories support, knowledge, technology, and every bit of information ever needed to fix and maintain all their products.. So they know what breaks and why.. They even know when stuff will fail within a few thousand miles.. Turns out the dealers are just heartless money hungry lying bastards.. I wish I learned what I know now a long time ago.. I would’ve been a plumber or something.. It’s great to know a lot and be a skilled auto technician, but there are way too many outside negative factors that come with the trade today

now do this in the salt belt

Damn fool! Not dropping a tank and changing the pump with an OEM one.

Dang that was a quick fix, nut loose behind steering wheel

Pump still good only the fuel gauge needs changing

Modern fuel tanks are pvc/abs material. Plastic swells and shrinks in different environments. That's said the factory sets your fuel gauge with a +3% difference to make up for the difference. So example. During the summer heat of your mileage gauge is saying you're getting 15.4 mpg. You're truly getting a solid 15 mpg. But ideally in the winter, it's true. Knowing this. If you start to notice a difference of 5%+ when you fuel up vs. what the computer says you used. Then you know it's time for injectors or pump. This is coming from experience. Take it or leave it.

If that was metal flake I would of cleaned the tank out, even though there's a filter on the pump

Sooooo, you didnt need to pull out the entire gas tank did you? You just had to look closer at the gauge.. great job..

Gotcha. A new seal does it..

Try removing those tanks where they salt the roads in winter. Also if I drop the tank or pull the bed to get to the tank for whatever reason the pump is getting replaced with an oem.

And she’s running….. Lmmfao

Just a few cans of bud light and it's fine

If you didn’t know how to drop a gas tank before watching this, trust me - you still don’t. Seriously do not attempt this. This is an expert level job. Like changing your oil times 100 (or more).

It would be helpful if there was a link pinned to the full video, since this is just a short, leaving out the important parts. Maybe it's here and I just don't see it. YT keeps changing how shorts work. There used to be a description for shorts.

Why didn't you check the "Fuel Pump Reset Button" located in the trunk before doing all that work...I'm just saying you were fortunate you guessed right ...

Michiganders watching with jealousy

So ther then the seal what was replaced? The first step isn’t to drop the tank. Its more like verify that you have to. What if the dash failed, or actually had no gas. Ive seen people run out of gas, and think they had some major issue.

What could cause a fuel gauge to slowly go up, after filling the tank with gas. Other cars it goes up instantly but in my 1994 accord it takes at least a full minute for the gauge to read accurately. Also in case this has to do with anything, my car is running rich, cause the spark plugs look black with carbon and I also smell gas at the exhaust after one spark plug failed

Ya you really showed us how to fix it..

Did you clean it off or just replace the pump

I didn't see a test from the fuel pump connector, checking the wiring and the gauge. This should be done first. It used to be 0-90 ohms, don't know if that spec has changed. Tank meters are expensive, and so is guessing.

Unless it’s actually broken. If ur running ur tank that low out of laziness. Laziness has dumb rewards. Never seen a fuel gauge issue on a cjdr so far unless u installed the fuel pump like a barbarian and damaged the fuel level sender. But I haven’t seen that either.

Finally someone knows how to removed the ring for the fuel pump using a brass punch!

Easier with a lift

Sorry you had to drop the gas tank. To bad GM still has not learned

That'll be $1000, sir

What might be other problems except the one you showed us?

No, this is how to replace a fuel pump...

Great video. I don't think I would be using a wet vac new gasoline.

it ain't got no gas in it. mmmmm

People always freak ouTT so easly whole TTime iTT be a small issue but tthe shop gon have u pay arm in leg 😀😀😀😀

Because it's broken! Lol 😂 now I will see you fix it.

I don’t understand how the fuel pump or the pump seal are in any way related to the sending unit.

Putting the fuel pump in the gas tank is one of the stupidest ideas of all time. I know they did it and it works, but still.

Now try this with a vehicle from NY😂

So you never did say what the fix was. Replacing the the whole unit is not fixing its Replacing.

Not changing a fuel pump for a bad gauge. Why GM? Year 2123, customer, fuel gauge does not work Mechanic/salesman, you need to buy a new car. It is a whole unit.

A vacuum cleaner and some solvent fumes were enough to almost burn a house down. Happened to a friend of mine 20 years ago. Be mega cautious about using vacuums with combustible fumes. Just saying.

How much was that new fuel assembly? For my 98 silverado, oem is hundreds. A separate issue i have is my fuel gauge needle vibrates really fast, it almost looks blurry, it's still fairly accurate though. I know it's not the fuel pump cause I've replaced it and didnt change the needle

A bunch of steps were missed due to the short format. Do more research before trying at home!!

You could do this difficult repair, or you could just sell it and buy a new one...

Ohhhhhhh GM, keeping skilled technicians in business year after new year. Long live the Check Light Champions!

Oh yeah bro, Awesome fix 👏 "and look at that " Great knowledge and Clean Work 🏁

Their is a proper tool to remove the lock ring. Instead of a hammer and a punch even if it is brass. Just Sayin

Changed the floater and nothing happened

Zoom out a little

How can you say this is why? What if it is an actual gauge problem or a wiring problem?

I LOVE that GM decided to make the fuel pressure regulator unserviceable by putting it in the gas tank !

Okay she's running but is the guage correct now?

I just got my fuel pump changed but before I didn’t smell gas now every since they changed it I smell gas inside the car the also change gasket
