2022 Duramax L5P FUEL FILTER CHANGE | GM 2500/3500 HD 

For those with a push button start rather than a key, hold the button in with your foot off the brake until the lift pump starts. Once the lift pump kicks on it’ll run for a bit and shut itself off. Once was enough. The engine fired up like normal.

The black stuff (actually brown) on the filter and in the bowl will be there no matter what fuel you use. It's caused by common rail and is called asphaltenes. The fuel is heated by the HPFP and by cycling through the injectors and back into the tank, and that causes it to degrade into microscopic particles. The particles are soft tar so they don't hurt anything, they just get caught in the filter. A lot of people wrongly think it's algae contamination and waste time with biocides, which are bad for your engine.

Thanks for the vid. That's a lot easier than my 2016 GMC 2500 where you had to pull the ps front wheel and inner fender

Much love thanks a bunch!

Thanks for making this!

Thanks for making. Got a 2023 3500 and can’t find any information in my manual or duramax book supplant on location or procedure. Ridiculous. Looks to be the same procedure for my international semi trucks as well. Thanks!

Bet the inner cap is to reduce the amount of vacuum off the filter housing allowing it to spin much easier

If you start to get the P0191 error code dealing with fuel rail pressures, even if your fuel filter says 20% remaining life, change it - that is primarily the problem.

Great video! You referenced some fuel additives that you add every other fill up and every oil change. Can you share what you add and when? Thanks!

Good job, keep those fuel injector clean

Hey, great video I had the same truck I was wondering what size rims and tires are running on it I was wanting to do 20 x 9 if it 35s but I don’t wanna have to really lift because that’s my daily driver I do construction. So what size rims and tires are you running and what is the opposite? Thanks so much I appreciate it.

Hello! Please, could you ask a question? Does the 6.6 Duramax Diesel version also have a fuel filter? Or just the gasoline version? Thanks!

I was so happy to see GM relocate the filter to a practical location & ditch the sensor wire.. you have a knob on the guage cluster to scroll the menu? Wierd, i have a 21 custom, i use the steering wheel buttons

Wow that's really low mileage I've got a 2022 that I bought in March and I already have 41,000 on it

I have the “Service water in fuel” warning. I took the water plug off, the T-30. Some water did come out, I put it back on, warning popped up again. So I have taken and put it back on several times, water dripping out every time. I am wondering if you don’t leave it off and idle the engine? Your thoughts?

Dealer charged a FULL hour labor on this today before I took the time to look it up. UGGGH Criminals.

Can I change the filter with a full tank ? Will I have excessive fuel drainage? Also , did you pour fuel onto the filter or did you install it dry ? I heard you say the you lubed the o-rings with fuel. Thank you

Whats the average mileage between fuel filter changes on these 15k? Do you wait for the dummy light to come on the dash so to speak or does the owner manual specify a mileage amount?

How do you prime with no key? I have a push to start ...

Yo man did u prime it? How do u do that on a push to start

Is it just one fuel filter? New to gmc I got a 2022 as well. I was told there are two fuel filters on some other trucks

2 pack on amozon is $20

is there just one fuel filter on the Duramax?

How much diesel came out.. any need to unplug batteries?

What’s the torque spec on the T30 Torx?
