I suggest a 6-point socket over a 12-point to avoid damaging the plastic filter housing. Lisle part #14500 will do the trick. Good luck DIY’ers.

To keep the plastic nut on cap from rounding off I put a piece of paper towel between the cap and socket and it makes for a more snug fit.

Good video. I appreciate your proper demo of the Priming process; other vids go straight to “Start” which isn’t correct.

Thanks, our Mechanic just quit without notice, so i have the shop i can use, and will try changing oil and fuel filters myself. 2021 GMC Duramax

Good tip on priming the fuel filter then starting the truck.

Thanks. After. 6 month wait, my ‘22 Duramax DRW arrives this Friday; saying I’m excited is an understatement.

[petershimkus]

Thanks for the tip of priming the filter a few times before trying to start.

FYI… next time, there is a small drain port in the center bottom of the housing. See how it works when you have it off. You can break the vacuum and capture any water/debris before you unscrew the cap.

Truly appreciate you taking the time to create this video, it was very helpful in so many ways - nice detail showing the filter prime - my '21 is so much easier than my '16 Duramax, they really made so many great updates between the two trucks!🙂

I am glad they moved the location. Hate them being in the front wheel well.

[hpcomcast]

Wonder if you can use the 2020+ def tank on the 17-19 l5p. Much better place then the eye sore it’s at now.

* Sorry For This Long Read * Thank you for this video. I got a job as a welder with a concrete company. I told them up front that I know how to weld, but that I suck at it. I also told them that i am a dedicated and fast learner. But then one day a hitch on a crane truck broke. They asked me if I knew how to fix it, and then one of their gasoline trucks sprung a transmission leak. I've been building cars since I was a kid. I said sure. Then they asked me if i knew anything about hydro systems, diesel and heavy machinery. I lied through my teeth. I said yes. I have no clue what I'm doing. And yesterday I spent an hour just trying to find this dumb fuel filter. So thank you.

My filter looked just as dirty/black at 11, 000 (2% life).
Great video, thanks

[jaydog]

I just changed mine at the factory specified time which my truck literally tells me to change it when its time and my filter looked just as dirty. So when yours said 100% i think you can trust it

[straightpipediesel]

You don't need a billet cap. I'd be concerned if whatever metal they used will rust and clog your injectors, and whether they metal threads are going loosen with the plastic housing. Just buy a new cap when it gets rounded off, the GM parts catalog shows it costs $7.28 MSRP. If you wrecked one every time you change the filter, you'd still save money.

[BlkGry]

The fuel filter being black doesn’t mean its dirty, if you check your new filter after 5 days it will be black already you cant tell if its good or not just count your miles

[jonniefraz]

Thanks for the informative video. The first time I got the filter from your link it was just as described. Bought one last week and it is not the same filter. No markings at all on the filter and the box was not AC Delco, just brown paper box.

[hvlineman]

Good stuff thanks for sharing👊. How in the heck do I run my radio without starting the truck, for more than 5 minutes without it turning off??? (2021 Duramax 3500 High Country)

[JonathanAyers]

quick trip back = couldn't do it by hand 😂😂

[RobertHolster]

I am going to change mine today!! Fun fact: I saw this video a couple of weeks ago, and decided to use the same skill set that you have...and purchased the 36MM six point socket😂.

Great video as always brotha!

Edit- I changed the fuel filter, and followed your process in detail. Startup 100% first time go. No leaks. We good! My filter was showing 20%, but much cleaner than your's. I'm thinking it was changed when it was last serviced prior to purchase but the indicator wasn't reset.
