Definitely. I was wondering if he replaced the pump or just the seal and cleaned the indicator brushes. More context would be nice. 3 - 5 minute video, perhaps
@@yorselrus1996 do you not watch him? If his head light bulb is out, he’ll replace the entire housing because that housing is probably original and 20+ years old
That's not really necessary. The fix was made. So, if you have either one of those problems..... BAM..! There ya go. Besides, it's called a short for a reason.. Lol.. 😂
Very true. The cheap chinesium stepper motors GM uses are junk. I ended up, after three separate failures (different one failingeach time), replacing all the motors in the instrument panel of my 03 Silverado.
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
Should always test it before you install it in the tank, (take the pump fuse out.) Some rigs you can also test the pump if you submerge it in fuel. Be careful.
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.
Common mechanical sence , you very carefully remove the debris that’s on the brush .. making sure that you don’t disrupt the angle of the brush compared to the Sister one next to it … ( how do you go about this is your business )
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!
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.
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 😫
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😂
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.
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.
I have a '60 bird, but with the 430cid option. Did you add an inline fuel filter?? Also good to add another ground wire on a corner of the fuel tank to a body ground. 👍
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.
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
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.
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.
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 ...
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.
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
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.
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
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.
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.
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.
Always test your pump yourself too if need to. A good pump will run 50psi+ at idle, and hold 40psi minimum shut off. Normally injectors are too blame for the difference. Hard starts, poor fuel mileage, no power that's a filter or a regulator
What yr is yours? Im asking coz if its a 05 envoy did you find your fuel filter? I cant find mine and dont really want to remove the tank just to find its not there.
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).
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
try measuring the signal coming from the fuel level sensor, ideally with a scope. Maybe the vibration is already in there. You can also check the power feed to the fuel tank, maybe the power is fluctuating due to a corroded connector. If all of these are OK then the problem is in your dashboard (these tests are of the category 'easier said than done' but it's nice to point at exactly where the problem is)
@Netherlands031 a year later I got a Bosch fuel pump assembly. The gas needle no longer vibrates. But it shows lower gas level than what's in there. Also she won't fire up after sitting over night
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.

Definitely. I was wondering if he replaced the pump or just the seal and cleaned the indicator brushes. More context would be nice. 3 - 5 minute video, perhaps
Yes, show the whole process.
I was wondering the same thing.
What was the fix?
@@yorselrus1996 do you not watch him? If his head light bulb is out, he’ll replace the entire housing because that housing is probably original and 20+ years old
And here I thought you were going to show the fuel gauge a final time, showing the difference.
That's not really necessary. The fix was made. So, if you have either one of those problems..... BAM..! There ya go.

Who cares ?!
@@garycasper2929 I’m so happy 😃 😊or 😊
Problems not always in the fuel tank or on the fuel pump sometimes it can be behind the dash
Or holding on to the steering wheel.

Replacing it only ensures your mind. Doesn't mean the new pump won't fail the same day

Yeah. Our cars in Florida also stay looking like new for decades. You should try it.
Or on cars that have proper rust prevention from the factory
I don't think california is better for rust...

I’ve never ever saw a tank etc so clean! We’re do you drive it? Indoors😂
Noticed he use a brass bar to drive the ring in place, because brass does not spark.
This guy is such a goof
And neither does a shop vac when it's full of gas fumes.😂
Everything is so new and clean and easy to work on
I noticed that too. LoL
When will you enlighten us on how you fixed anything?
Next week same time same station. Now stay tuned for the evening news.
Turns out my car just needed more gas and not just $10 every two days
👀😂😂❤🤑
Filled up Thursday, started up Sunday, no crank /start😢
Just remember to fill up when the gas gauge hits a quarter tank and you won't have to go through this needless repair.
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.
Br0,Your gonna have a whole new truck when it’s all said and done! Great channel! Keep it coming
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.
Wow, the cost to fill a 62 gallon tank is more than the value of my vehicle.
😳

Better to either brush it off or use air to blow off the dirt. Then wipe it down if needed.
So if I see that the brushes are dirty I can just put it back together and it’ll work?
You never know since he did not specify
Common mechanical sence , you very carefully remove the debris that’s on the brush .. making sure that you don’t disrupt the angle of the brush compared to the Sister one next to it … ( how do you go about this is your business )
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 !!!
A dam rag all you need to clean the top of the tank
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.
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!
If you never let the guage drop below 1/4 tank you'll never have this problem. The fuel cools the pump.
You ever seen a more pristine server come out of a vehicle looks factory new
Easy job when it looks like new!! compared to rust buckets!!
Make a pump access door! I did last month and love it!
If you were in Wisconsin, you would be replacing the tank, too.

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

I think he, & that truck, used to live in California.
I know that rust issue very well and the plastic gas lines that seized to the metal line
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
Thought it was ethanol thing at first.
Upload a video putting a 12450086 lamp 💡 underhood in a 2004 Envoy with 25751099 harness underhood ??

Lol 😂
I've used electric contact cleaner and a brass brush to clean them before. Bend the feelers a bit more for extra pressure. Works well!
@@bigpjohnson thanks for some real info unlike the guy that did this video
Ur gonna want that tank empty and be outside. The fumes are very strong when the pump is out

How he tightened the fuel pump I assume he took it off the same way! Good jewel dropped there
I love how easy that is I think I'll do it tomorrow after work and be at work in the morning
Wow…was the gasket not grounded or what?
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.
Notice that he is using brass to put the ring back on. It 0nly tales one spark to blow yourself up.
I'd be cursing the engineers.
Did you clean it off or just replace the pump
That was a new fuel pump.
It's easier to remove the box.
