- How to fix a fuel tank leaking gasoline on a 2015-2020 GMC Yukon, Chevrolet Tahoe, Chevrolet Suburban, Cadillac Escalade, and GMC Yukon XL. If you smell gas fumes or see gas leaking from your full-size GM SUV it may be a simple DIY repair instead of taking it to the dealer. I’ll show you how to depressurize the fuel lines, disconnect the fuel and emission hoses, and lower the gas tank.
As long as you can safely raise the vehicle and support it with jack stands you can replace the problem fuel line with a few basic tools. This is a DIY method for completing Technical Service Bulletin 17-NA-304, Condition 2, Fuel Leak.

Thank You Thank You Thank You for this video. 2015 Chevy Suburban LTZ, same problem, same solution. I followed this video step by step, and it helped. Took me a while, but it was worth the savings. My biggest struggle was I could not see the top of the tank, I had to feel my way around to disconnect the old line and connect the new line. GOOD LUCK EVERYONE
Glad you got it fixed and were able to do it yourself.
Same problem and same solution for 2015 Tahoe LTZ. Great video, I followed the exact instructions. It took me 2.5 hrs to complete. Big win for sure!!
Sweet! Glad you were able to fix it cheap.
Great video! Saving money is always good. Dealer is in business to make money from those who will over pay or are not DIYs! Thank you for your content Ray!
Oh the joy of working on vehicle with so little rust!
My '06, not so much
Thank you for this video! My 2015 GMC Yukon SLT is leaking the same way! I'm headed to fix her now! God Bless you brother 💯
Good luck! Be careful!
My 2015 Tahoe LT having the same issue, Thank you for the Video it helps alot
Exactly what I thought. Nice job! I'll be doing the same thing this weekend. Dealerships are money hungry.
If I wasn't treated that way I would have gone back. No chance they ever see me again.
Dealers always over charge ppl..u did the right thing.....they would not have told u the truth....great choice
Thanks. It's really sad that I don't know anyone who trusts any car dealer for service.
@HouseDoctorRay Thank you for the solid video with good information, and the links. Because of you and your video, I was able to fix my wife's 2105 Suburban in about an hour, and back on the road she goes. Keep up the good work brother!
Glad it was useful to you. Thanks for watching.
Great help to me. Me and my son knocked it out. It was hard getting that last valve to unsnap between that rock and a hard place. But we got it. 🤙🏽
Nice! I hope you saved a ton of money.
Great and very helpful video thank you
Exact same issue - 2016 Suburban. Thanks for the exact steps to fix it!
Good luck Tom, keep those wheels chocked.
Thank you for posting and the good videography.
Thanks, it was tough getting the camera in some of those spots.
2015 Tahoe leaking in the same spot.. Thanks for the video!
Great video it seems I have the same issue with my 2015 suburban ltz! Thank you for the instructional video !
Hope you're able to fix it.
Perfect fix thank you
Very helpful, thank you!
If that fuel line vibrates excessively at idle, you also need to replace the check valve fuel line at the engine,
otherwise it will happen again soon, and you may actually get a hole in the tank next.
The upgraded line with the braided sheathing is *very* tight where it snaps into the tank. I doubt it will rub there again.
But you are correct about that line under the intake.
Very helpful! Thank you!
Glad you liked it. Hopefully you don't have a fuel leak.
Same issue here , I will look this up and see if it’s the same problem . Thank you for the video .!!
Good luck! I hope it's an easy fix for you like it was for me.
Thanks man , this solve the issue . Once again thanks for the video 🫡🫡
Thank u sir mines was the same issue I followed ur steps and bought the same fuel line ! Perfect and the same pin hole like yours thanks so much very helpful
8:11 done 3hr job in my carport
Excellent work!
Thank you. Have same problem on my 2016 suburban
Good luck. It's not that hard if you don't have forearms like Popeye.
Because they tried to make more money off your ass. It's what they do. But good thing you fixed it yourself. Things are always cheaper when we put the work in ourselves. Good job and Thanks for sharing your video.
Great video brother! This was a great help with my 2015 Cadillac Escalade. I was able to take care of my leak in about an hour and a half.
Awesome! Glad you saved a ton of money doing it yourself.
What did you do to fix
Good job
Thanks Clarence
Well
U r a trooper
Can u imagine how many folks
Continue to fund these leak
Jobs and other defects
I have worked for a few
Not all are that way but
Most will mis- diagnose
Bcz they fail to do proper
Inspection and diags
The service rep wrote it up as needing a gas tank. They gave me the mechanics notes as part of papers when I picked up my truck (obviously not intentionally, they wanted me out quick). The mechanic wrote 'tank needs to be removed to determine where leak is'.
The service rep emailed me the $8,000 estimate without even a heads up phone call.
To tk very much for you help
The price of the flex pipe was ridiculous....lol
I have to replace that right now. When i was looking at it i noticed the leak. The exact same leak you have in the video.
So now i will tackle both.
I'm sure the $3,500 for the flex pipe doesn't include them going at the bolts ice cold. Snapping them; then the studs in the head. Would've ended up being $9,000 by the time they finished butchering it.
problem just happened to me last night on the way to Grandma’s house. In drive thru of Mcdonald’s, my wife noticed the gas smell. Thought it was the old pickup exhaust in front of us. Got to Grandma’s peaked under with a flashlight… same drip, near the midsection of 2015 Yukon XL - and only when the engine was running. leak is driver’s side, below where the front and 2nd row seats are situated.
Of course on July 4th.
Bummer. Some people have had luck at the dealership getting this covered.
It's not that difficult to fix yourself as long as you can safely lift the truck up a little.
Thank you so much, I accomplished on my 15 Escalade without too much trouble, found a similar pin hole half way up the fuel line. Its suprising this isn't a recall due to it being an explosive category failure.
Glad you got it fixed. I guess it will be a recall once one of them catch on fire.
Have the same problem on the pickups
Thanks for the video. Great information. The only comment I have is that you should try to remove the tank strap bolts by hand with a ratchet instead of using an impact wrench. My son and I tried doing this repair on my 2015 Tahoe. He used an impact gun on the rear strap and ended up breaking the clip that holds the bolt to the frame. The forward strap bolt came out using a hand wrench without damaging anything. In the end I had to take the truck to a dealer because we didn't have the tools to remove that rear tank strap.
Sorry it didn't work out for you. I hope the dealer didn't hit you too hard.
Same issue here, I read this comment and didn't use an impact wrench, just a ratchet. The back came out fine, but the front strap bolt has a nut that's up bolted to a frame bracket that you can't see and the weld came loose. This wound up with the bolt just spinning and unable to remove the tank strap. The only option then is to cut the strap or cut the head of the bolt off, which I was not inclined to do given there was fuel all over from the leak, and the tank is plastic and likely easily damaged. I spoke with a mechanic and he immediately knew how to fix it given he's dealt with this many times before. They cut the strap in the center, remove the tank, clean all the fuel residue, and cut the bolt and replace it with new.
This is a very informative video. My only advice is do not use electric power tools around your gas tank. Maybe just pneumatic tools. Any spark would not be good. Saw a video where a whole shop burnt to the ground because a guy was using 18v Dewalt near a gas tank.
🥺
Didn't even think of that. Thanks for posting.
Hey man, thanks so much for the video. Wife just noticed gas smell on her way home. Googled it and your video popped up. When she got home it was leaking same spot..
Question, we have a 2015 Tahoe. The link you provided on Amazon says not compatible with 2015 Tahoe. Do you know if I should just use that one?
Try this one:

Thanks so much man!
Upselling the new tank rather than really diagnosing the real problem
Really sad. If they would have told me they had to drop the tank to find the leak I would have said, "go ahead". When they told me I needed a new tank I was more than annoyed.
One of the hardest jobs I’ve ever done. It took me around 2.5 hrs.
2.5 hours doesn’t sound to bad
Especially when it saves you hundreds of $$$.
When you do the fuel line on the g m c u con do you have to drop the transmission
Absolutely not.
It’s sad , I had a dealer say I needed a new catalytic converter because it was clogged. I had no power to climb hills or go over 50mphs. I took it to an independent mechanic to check it out. I couldn’t afford what the dealership quoted either. The independent said he’s never heard of a Chevy truck converter clog. Left it over night and he had it fixed in the morning. All it needed was a fuel filter. It was a big one up in the frame towards the back. He said it must have been the original one as it was still covered in factory undercoating. It ran perfectly after that. That was over 10 years but the same type of dealing.
Glad you didn't get got.
I need to replace a fuel line on my 2004 Yukon but it's parked outside in a foot of snow and -33 below wind chill.
That's a bummer. Although the snow is probably high enough to block the wind while you're under there.
Keep watching @HouseDoctorRay until it's over.
stuck in 115f weather right now, when I turn the key it starts leaking under the driver door handle. all before it’s running. when I start it, it takes a long time to start (3-4 seconds) and idles at 450-500 rpms, any idea?
There is an electric pump in the tank that sends fuel to the mechanical pump under the intake. It's probably the line I changed in the video.
Hello, My 15 suburban is leaking in the same area, is dripping down and only when running in the same area as yours. This sounds like the same problem that you had, Is there a reason this is not a recall and not replaced for free? Thanks!
Some people have been able to get it covered by the dealership. I was not.
Look in the video description, there is a link to the Service Bulletin. Print it out and take it with you.
Call Chevrolet customer service before you go and log a complaint about the fuel leak. They'll give you a number to give to the dealership.
Have the service manager watch House Doctor Ray's video.
Shame on GM dealership for false service claim you can’t never trust the mechanics now days this is getting dangerous on dealerships if they tried to rip you off for 8k and you fixed it with 50$ this is scary can’t trust GM we as people should sue them this is FRAUD on GM I’m pretty sure they knew it was you’re fuel line just wanted to steal you’re money good job for this amazing video
Thanks Don
O just changed my 07 Yukon fuel pump. The shop quoted me $1200. I bought the fuel pump from Rock Auto for $150. Then I took four hours to change it out. It was rough, but I got paid $250 per hour. If the shop has done it it would have taken them 2 hours at $500 per hour.
Nice job! Luckily my fuel pump is still going. It would be tough for me to get the tank out from underneath.
That's allot of gas. Thanks👌💯dealer ripoff😝
Sure was. I had no symptoms before it started leaking. Just pulled to a stop and thought, "wow, I smell gas"!
Just did this on a 2015 Escalade. Had fuel smell no visible leaks. But line had several weak spots in it.
I hope it fixes your issue.
Same here I can smell it when I step on the gas while I'm driving... Quick question did the gas smell go away when you changed it??? ............I also smell gas but i see no leak..
I'm getting ready to make this same repair this weekend. I took it to a dealership thinking this had to be covered by a recall. Instead, they quoted me $2000 for tank and $4000 for the total job. I told them to drive my Tahoe out of their garage and I would pick it up. They ended up charging me $175 for Diagnostic stating they ran a smoke test and it was leaking from a seam on the tank. I ordered the part today. Once fixed, I plan to light the dealership up on Yelp. Ridiculous service from dealership. GM needs to recall this before cars and potentially houses catch fire due to leaking fuel.
Good luck. Post back when you're done.
@@HouseDoctorRay
Just finished the repair. Same situation with dealership (incorrect diagnosis), and same exact fix. Followed the instructions exactly as outlined in your video. Had a bit of trouble buttoning the fuel tank back up (it was ¾ full and heavy), but I got it back up.
You literally just saved me $4000.
If there was an award for easiest fix in portion to highest estimate from dealership, I dare say you might win the prize. You should be standing on the stage, excepting the award, and thanking those that made your video possible.
You are a legend in my books. A man among men. Hats off to you sir.
Thanks. Glad you got it fixed and saved a ton of money.
I still get pissed every time I think about what they tried to do to me.
Hey thanks for the video, I've got to the point where I'm unbolting the strap to the tank. The bolt is loose but it just keeps spinning and I cannot get the bolt outs driving me crazy
Gotta try and grab the nut on top with vise grips.
@@HouseDoctorRay unfortunately there's no access to the top side... Any ideas? Thanks!
Angle grinder.
Carefully cut the head off of the bolt without damaging the strap.
If you don't have one Harbor Freight has them cheap. I've had one for years from there. I also have a Metabo from Lowes which is inexpensive. Both are good enough.
@@HouseDoctorRay Thanks for that and I'm assuming The sparks from that should be OK near the gas tank? Also can you send me a link to the replacement bolts?
As long as there are no fumes. I would still put cardboard or a piece of wood in the way.
You'll have to source replacement bolts and nuts locally. If you have a Fastenal or Grainger's they should have them, maybe auto parts like NAPA. I wouldn't use those cheap zinc bolts from the hardware stores. You want a grade 5 bolt. Some hardware and construction stores carry them.
Your best bet to get it tightened up if you can't reach the top is:
Feed a long bolt down through the hole with a split style lock washer under the head.
Put the strap on.
Put a split washer and regular nut on.
Tighten up.
As everything gets tight the lock washer under the head of the bolt should keep it from turning. If it doesn't stop it from turning you can always grab the bolt below the nut with vise grips.
Get the longest bolts you can feed through. If you need to you can always cut off excess after everything is tight with your new angle grinder.
Good luck.
I have the same problem now
Sorry to hear that. Check the video description for a link to the Service Bulletin. Some people have been able to get it covered through their dealership.
Hi my friend where is the fuel filter location I have same car I can’t find it please help me Tk
Filter is inside the tank.
I CANNOT get the fuel tank to drop. It appears some white plug on the front of the tank is catching on the central cross member and I cannot slide the tank back or forth enough to free it. I have the jack stands on the rear axel. Maybe the jack stands need to be supporting the frame instead?
It will only drop a few inches unless you remove all the hoses in the back. A couple of inches is enough to reach over the driveshaft and remove the line.
@@HouseDoctorRay I see, I was indeed able to do that I thought the front end would drop all the way down but I was mistaken. Also, is there some sort of insulation on top of the fuel tank or was I touching a mouse nest..?
The only thing up there is that gooey black stuff. You better wash that Hantavirus off your hands.
Just got an 06 escalade for next to nothing with the same issue hopefully it's the same $47 dollar line
I hope so too but the line is probably different.
Hey House Doctor Ray, I was watching some videos on leaking fuel tanks for my 06 Suburban and came across your video. I am having the same issue and was told that I need a fuel tank, I see it was the Abeloff Dealer on 611 in Stroudsburg, PA. I live in Mount Pocono, PA. Do you do work for people besides your own? If so let me know I would appreciate any service you can provide. Thanks and Awesome Video!
Yes, I'm in that area but I don't perform vehicle repairs. HOA!
If your's is anything like my 06 Sierra you probably have a rusted fuel line. I've replaced all of my lines underneath except my fuel lines. They're getting done this spring.
The guy who owns Cherry Valley Tire & Auto has always been straight with me if you're not up to doing it yourself.
@@HouseDoctorRay Yeah, my fuel lines were done a month ago. Thanks!
You didn’t need to take the filler hose off at the rear, to drop the tank further? Removing straps alone, barely dropped it enough.
It was tight but I got in there. Popeye couldn't do it, but there's enough room for regular people.
Thank you ray, we got it!
Had the drip in the same spot
Dropped the tank sending line was bent but just case I am opening the tank to make sure it’s the line
Do my truck have to be on a ramp to get the tank half off
Depends. Mine has running boards and I'm a little husky so I put it up on 4 Jack stands.
Appreciate the video got mine 2015 Yukon fix👍🏾
Just standard Dealer procedure. Charge the customer a high price. Actually do the low cost work.
Sad way to run a business. I feel for the people who don't know better. I would have paid them $700 to drop the tank and replace the lines.
They were too greedy and got nothing from me. They'll have to make it up on old people and people who have more money than sense.
What happens if the fuel line is pressurized?
You'll get a small mess. Wear goggles.
Yes, I'm having the same problem. I believe I can do this, unfortunately I have a full tank of gas, smh
Go for a long drive...
I have the same problem on a 2015 Chevy suburban
If you're a little handy you can do it. Some people have been able to get this covered out of warranty. Check the video description, there is a link to the Service Bulletin.
Me too
The repair is as easy as it looks in the video. As long as you can get it up high enough to get under and don't have forearms like Popeye It's very doable.
@House Doctor Ray thank mine just started yesterday and we git 8 inches of snow last night it will be fun
That's a bummer. Mine started right after a fill up. I drove it for a week to get the gas level down. Unfortunately on my 15 there is no way to run to pump to empty the tank.
Mine leaks only when I start the car...after shop replaced the pump
That's not good. Take it back. There is a link in the video description for the service bulletin that describes the problem and the resolution.
They probably thought they were running into somebody.That was very stupid and they were gonna take them for everything that it was worth.Dealerships or nothing but rip-off.Artists don't trust them never did never will
Can anybody help me?? I started smelling gas only when I accelerate and I have the windows down I can smell it when I step on gas I drove it for a while but still I do not see any leaks dripping from the tank anybody else have the same problem
That might be your high pressure fuel pump. It is under the intake at the back of the engine. Pull your dipstick and smell the oil. If it smells of gas it's likely that pump.
It should be noted.
1.This is not so easy without taking the tank completely down. Wow was that rough.
2. Have some extra tank strap bolts. One of mine broke the nut.
Dorman 55157
3. Don’t do this if you’re claustrophobic.
Having worked on a lift before I can say doing it the way I showed would be more difficult on a lift.
I was able to lay on my side facing the tank and get my whole left arm in there. On a lift, at a minimum, you would need to remove the driveshaft to get in there.
That Yukon sounds rough running..but fuel pump seal might be rotted
You talking about the high pressure pump under the manifold?
i have the same problem
Bummer. It's not that hard. Read the comments, many people have done it.
Actually in a lot of them it is a cracked tank and they are on national back order. Oddly, they only leak while they are running.
I don't understand how that is possible. What would cause the gas to leak only while the engine is running.
@@HouseDoctorRay We're doing one right now. Crack is right under the front frame attachment for the strap. Had to order from a recycler due to none available. I was sure it was going to be what you found.
But why does it only leak when engine is running?
I bought a 2015 tahoe and about 3 weeks later, same leak occurred. Took back to dealer and they tried to charge me 1800 to replace fuel pump.
It's a shame that they're either incompetent or worse.
Tech at the dealership just being lazy, lifted truck saw gas pouring out and knew he had to take the tank down anyway.
Thanks for the Video
Wow so much rost. Need to change the fuelpump of my 2017 suburban.
The bigger problem is getting all those lines at the back loose to change the pump. You should change the line I did in the video when you get it down. It was worn bad at 140K.
Was just thinking. If you have a lift...
Disconnecting just the front lines may allow you to drop the front of the tank enough to get the pump out.
Those back lines are really tight and you may have to cut them or use a heat gun to get the big one off.
@@HouseDoctorRay thanks for the tip. Yes i have a lift. Will try that
Seems to me general motors would fix this pretty quick. Before a lawsuit
There is a link to a service bulletin in the video description for this issue.
I've read on some of the forums where some customers were able to get this covered by corporate.
I guess the 10 or so vehicles I've bought new from GM mean nothing to them.
They want to make invoice orders to warranty companies so they order the entire units new. Just how corporations function with insurances and warranties.
Alright but I was over 100K so nothing was under warranty.
The dealer said a new tank because he new what the problem was, new how much it would cost, and new there was a chance of repeat custom when the leak carried on.
So I should have paid them $1,400 to replace a $50 part that would take 2 hours to do?
@@HouseDoctorRay That is not what he said. He said the dealer wanted to hook you like a sucker.
The dealer pretends to sell you the right stuff, have you coming back as a repeat customer to solve the same issue.
My bad. Either way they didn't get my money.
They also wrote up, "rotors rotted, truck doesn't stop good". Really sad what they do to people. Pads were fine and less than 1/4" corrosion at the edge of rotors. Passed inspection at a private garage a week later.
@@HouseDoctorRay That is how the dealership make money. You were lucky they didn't try to sell you a new car while they were at it.
That is why I am protesting for them to change their names from 'dealership' to 'stealership'.
I looked under the driver, there is nothing.
Fuel filter is part of the pump assembly inside the tank.
hi my mum car is doing the same thing maybe you can come over and help please
Jason, call GM customer service and complain. Some people have been able to get extended coverage.
Surprised a fuel line leak is not a recall instead of just a TSB. Also with your invoice, stay classy GM. Trans lines, oil cooler lines, lower pan gasket. 😂 Replace the trans, oil pump, cam and lifters, and brake vacuum pump while you are at it to fix all the common problems with those trucks. 🙄
At 156K tranny and lifters still good 🤞
I have the same problem on a 2015 gmc yukon
Complete bs this isn’t a covered warranty recall
Call GMC customer service. Mention the service bulletin I linked in the video description. The leak is 'condition 2' in the bulletin. Tell them House Doctor Ray sent you!
www.gmc.com/contact-us
Most will choose the bigger pay
Day option
Why replace the hose when
One can replace the tank plus
And charge you for half the
Value of the suv
Think about it.
Sad but true
I cannot get that dumb clip on the top of the tank off.
You can do it!
There is a little tab you need to pull towards the driveshaft.
I got that one. Can’t get the blue clip holding the fuel line on. Any tricks to it?
Try twisting the line slightly as you push towards the tank connection. If there is tension on the line the clip gets wedged in place.
That clip comes loose the same way as the two blue ones in the front.
Got it. Thank you!
Dealers are like politicians..... if you know what I mean
You got that right!
The dealer committed fraud.
Well,...
It was only an estimate. If I attempted to pursue it I'm sure they'd get off the hook, "we would have seen the line when we dropped the tank". I'll leave it at I'm never going there again.
They wanted to make money off of you. They would have listed a lot more if you had bumber to bumper warranty or even just an escalade.
Probably right.
Excellent video!
Thanks
They are actually "STEALERS" NOT DEALERS.
Got that right.
$3470 flex pipe??? 💯dealer ripoff😝
But the new one is extra flexy.
😆
Find a new dealer. Don't give them a penny of your hard earned money and also post a review on google of their dishonesty to warn others
i think ya lied
About?
There trying to screw you over
They must get away with it often.
I would have sprayed those fuel sender steel lines with some rustoleum...stop the rust
Good idea. I'm going to drop the tank back down and spray them right now.
Thanks.
