I'm in NE & my '05 Yukon XL is an '05 from out innthe country in SD. So much dirt & gravel innthat recessed pump area just holds moisture in contact with it & mine actually looks worse than yours. I'm still trying to remove the pump & will be replacing the fittings attaching the lines into the pump as even after two days of soaking regularly with PB Blaster & warm weather both lines broke off inside the fitting. Now I'm just hoping I can remove the ring & save me the cost of replacing the tank. Boy, the timing for this is really poor for my family. Thanks for the encouraging video.

[@henrikjonsson4340]

Great job AND you challenged it and tell us that it is not that easy all the time ... its not a 5min job...ALSO you warned about the dangerous with gas. Great vid!

[@P46345]

I've got a 2001 Silverado, it's a California truck and I live in Arizona so the lock ring has never had to be replaced, but to get it loose I used a BIG pair of Craftsman channel lock pliers. ;-)

[@xjohny]

I see that the fuel pump was still working, but all that struggle only to get the new lock ring out? I would replace the fuel-pump while in there just as preventive maintenance. I did it just last weekend on my 01 Tahoe and my lock-ring was badly rusted too. I spent about 45minutes hitting it from several spots until it came loose. I was almost prepared to order a new gas tank, lol. But fortunately the holding tabs were in good shape and no damage was caused to the tank.

[@jeffro221]

Nice job. That lock ring was a tough nut! As to what you said about how these days replacement parts are dicey, I totally agree. Even good names! It's obvious that buying parts on eBay is going to get you chinese junk. But now, Amazon also has lots of counterfeit parts being sold in OEM looking boxes. Many people don't believe that about Amazon, but you can rest assured that Amazon does not thoroughly vet all their 3rd party sellers. Not as bad as eBay, but they can't be trusted either. I have 4 vehicles at my house, from 1994 up to 2006, Buick, Ford, and Chevy, with 75k up to 145k miles, and all of them are still runnng on the original fuel pumps. I have now procured replacement fuel pumps for them all from Rockauto, but as you said, I'm not going to take out the originals until they bite the dust. Any replacment , even GM Genuine and Delphi, will not be as good as the originals.

[@vipersniper843]

Hope the pump does not die in a week after you get it back in . I cut a access hole in the floor my astro / safari van to replace fuel pump . a few rivets, seal it up job done fast .No tank removal . makes changing pump a lot less work ? Good job .

[@mossman381]

Did the same thing with the S10 and years later it's still working. With new brake lines, front brakes, fuel neck, wheel bearings, master cylinder, battery, blower motor resistor you have to draw the line at some point. I think it's getting close to $1000 in parts.

[@frenchonion4595]

It always makes me laugh when a guy out in a california shows you how "easy" it it to work on these truck's Rust makes everything a huge pain in the ass. I am highly tempted just to part mine out and go down south to get a clean truck and fluid film it right away lol

[@mossman381]

Amen!!

[@constructiontech1970]

Did my 2500HD fuel pump earlier this year and those lock rings for it can be a real bear!

[@mossman381]

Got to love rust.

[@akeemmuti6282]

Would wd40 work to help lock move?

[@mossman381]

PB Blaster is way better than WD.

[@akeemmuti6282]

@@mossman381 thank you 🙏

[@brianshult6908]

Another option to get at fuel tank is to remove box bolts on driver’s side and loosen on passenger. Then tip box up and support with 2x4. No need for tank removal. Worked well. I had to beat my locking ring into submission...😁

[@mossman381]

Tahoe, Suburban and Avalanche you can't tip the beds :)

@@mossman381 doh!

[@HODMEChannel]

Our winters in the salt country aren’t very nice to us. Hate to see what a new truck looks like after ten years.

[@mossman381]

The metal is also thinner. Another worry with getting a newer truck (07-13). I see 07-08 trucks rusted out.

[@billherzog5375]

Replacing the lock ring and seal on my 05 caravan tomorrow because of a leak hope it helps my ole clunker run better too lol

[@LynSkyn1981]

Same issue with mine I got a 2011 Silverado 58,000 miles on it and I have to replace the lock ring and I might as well just replace the fuel pump also

[@mossman381]

I use to replace parts while I was working on something like this. With all the bad "new" parts I seem to get these days I question changing OEM parts that are still working fine.

[@LynSkyn1981]

@@mossman381 yeah but I heard once you take the lock ring off you can damage the fuel pump or it's a pain in the ass to get the lock ring which is all rusted off to get the fuel pump off either way though I did buy a fuel pump and if I have issues with the old pump or if I don't have issues so I can always return the new one back to AutoZone

[@tjs_welding_and_fabrication]

Bad design. That valley keeps all the sand and salt in there. Not sure why you did not replace the pump assy while you had it out. Both my escalade and tahoe had fuel pump fail. Replaced the rings too. Delphi pumps have been good to me.

[@mossman381]

When the pump fails I will replace it. Did the same thing on the S10. Left the old fuel pump and it's still running. With the lift and a new lock ring, dropping the tank to replace a pump won't be a problem. Plus saved some money not buying a pump. With new brake lines, front brakes, fuel neck, wheel bearings, master cylinder, battery, blower motor resistor you have to draw the line at some point. I think it's getting close to $1000 in parts.

[@farmboy30117]

Probably would throw a code for an air leakage too. Looked like a pain to get that ring off!

[@grumpy1311]

Scary what hides underneath... Tough to get any fluid film up in there with tank in place! Merry Christmas

[@mossman381]

Sprayed it all down with Fluid Film before reinstalling tank :)

[@nascar5410]

I done even buy replacement parts in the stores anymore, only order acdelco on amazon for a cheaper price then the junk in the stores

[@mossman381]

I agree

[@fallenskyshomesteadingandp2528]

I hear what you are saying about replacement parts, just got burned on a water pump for Chrysler. Smh.

[@mossman381]

Happens way to often now.

[@tuckergarland9066]

I know this is off subject but I have a 2000 Chevy Silverado 1500 RWD with a 1.5 leveling kit. I was thinking of putting custom wheels on there, I seen your 2000 you had. You put 20 x 9 rims on yours with 275/55/20. I was wondering if there is any way I could run a 20 x 10 with a smaller tire on my truck without having to cut or trim out the fender well?

[@mossman381]

It's hard to say what combo will fit when you change rim size. That usually changes offset. A smaller tire will help fit your fender but then you get a small sidewall. I don't like the small sidewall look. Any reason you want a 10"? The 20x9 is a great size for those trucks.

[@tuckergarland9066]

Ok thanks. The reason I was wanting 10’s were just so that they would stick out farther

[@mossman381]

The farther they stick out the more chance you have with hitting the fenders. And they throw stuff all over your truck. Pretty much say goodbye to ever having a clean truck unless you get a drought.

[@MrTylerg506]

Have you seen Auxbeam’s quad-beam series led light bar? You should get one and try it out

[@mossman381]

I think I saw them. Maybe they will send me one.

[@MrTylerg506]

Cool maybe

[@jbow1488]

Thanks video helped A LOT

[@sgtw4902]

So what do you do when the ears on the tank break off?

[@mossman381]

You need a new tank.

[@reax2237]

Good job, maybe some fluid film on top to keep that from happening again. That rust is a bear!

[@Stevo-xe9jw]

While you did a great job, my lock ring is in way worse shape than yours, and I don't know what to do. The outside tabs are gone, and my first attempt with a hammer resulted in chunks of the lock ring coming off. Not sure what to do. A new gas tank is almost $600. It's welded in place.

[@mossman381]

If your tabs are gone the only thing you can do is get a new tank.

[@TheHomeWrencher_1776]

@@mossman381 actually, I have repaired these tanks using a new lock ring and drilling about six poles equally spaced around the outside perimeter, and then installing self tapping screws through the lock ring into the tank. It gets a good seal using the original rubber O-ring gasket that comes with the new fuel pump if somebody’s replacing the pump and then you can order the new nylon fuel line kit as well because if your ring is that Rusty your fuel lines are as well. I’m going to have a how to video on my channel coming soon on the same exact procedure as I am doing it on my project Escalade truck. GMT 400 platform.

[@ErrorlVlacro]

Can’t you cause a fire using a vacuum like that?

[@mossman381]

I can't say I have heard about that but if you sucked up a lot of fuel vapor, I could see that being a problem. When you are dealing with fuel you have to be very careful. I think I said that in the video. Fuel is highly flammable, and most people find that out after starting a fire. Please be careful if you are attempting this job. I would recommend having a professional do this job.

[@miket8571]

what did you soak it on

[@mossman381]

I use Blaster.

[@KTHKUHNKK]

@@mossman381 I'm curious why you did not get a new lock ring ?

[@Nordic_Mechanic]

I never take the driveshaft out to drop tank on pickups.

[@mossman381]

99% sure the driveshaft has to come out of 99-07 trucks to get tank out. I am 100% sure on S10 trucks the driveshaft has to come off.

[@mossman381]

Just went back to my video on the 1500 I took the gas tank out of. I didn't remove the driveshaft. I guess I was thinking about the S10 trucks.

[@xjohny]

@@mossman381 Just did fuel pump replacement on my 01 Tahoe and did not remove the drive-shaft. Although it may help with space around, it's really not necessary. I also didn't find it blocking an access to fuel tank connections.

[@friedsnow]

I use heat with metal rings dont catch on fire tho. Heat expands it

[@mossman381]

I won't use any kind of heat on something like this. Fuel is highly flammable and can ignite very easily. A lot easier than most think.

[@DreamTheory1994]

i dont think this is easier than a pickup. you actually have to drop the tank here. a pickup you just drop the bed bolts and slide the whole bed back to expose the fuel pump.

[@mossman381]

I guess that depends on the condition of your truck. If you have a rusty bed and rusty bed mounts it won't be so easy to unbolt the bed. And get the bed bolted back down.

[@DreamTheory1994]

@@mossman381 i wish that was the case. ive got a tahoe from up north and everything on IT is rusty. the silverado is almost rust free....

[@MaroLuva]

Horrible design. I had to let PB blaster soak on mine for a few days as well. Wanted to drop by and say you may not have to replace the tank if the locking tabs are gone, there are some kits on eBay that use self tapping bolts and a special retainer.

[@mossman381]

Just did another one on a 2005 Silverado. Same problem with rust. I suppose they could have used all plastic pieces that screw on but you never know if they would have had issues with that too. It's easy to sit back and say something wasn't a good idea. They have to balance cost and quality.

[@Leatherkid01]

Ive had a non oem fuel pump lasting 5 years+...

[@mossman381]

Glad you got a good one. I just don't trust parts anymore. I have a power steering pump and steering gear I still need to replace after spending time replacing them :(

[@Nordic_Mechanic]

@@mossman381 didn't I warn you? hehe red gear for steering and factory gm power steering pump is the safest option. I'm actually duramax ps pump change speed runner because of bad rebuilt pumps....sad

When anybody asks I tell them get GM new parts.

[@547Rick]

I understand the lack of trust in non OEM replacement parts.

[@grumpy1311]

Big time

[@mossman381]

Yup, if it's working I am going to leave it alone. With just over 100k miles the pump should be good for a while yet.
