VSE Dual Fuel Filter System Saver 3.0 Duramax Diesel Upgrade 

Appreciate the video showing the installation process. Being new to diesel engines and weekend mechanic, this will help me with the do's and don'ts installing this fuel system.

Thanks for posting this install. I have a 2023 Sierra SLT with the LZ0 and am thinking about this mod. especially considering the fuel these days! I do have an IDASH which I mostly use to keep up with the REGENS and other parameters. When you change out the fuel filters for this new rig it would be nice to cut them open and see what’s inside.😮

Also VSE sent me a complimentary set of Baldwin filters as they have had a lot of issues with the Donaldson filters leaking.

Got mine installed today and like you said always good to double check tightness from the manufacturer, my water separator adapter was loose and the inner o-ring wasn’t on the housing already so I missed it and had a leak after installing mine, until I looked closely at your video I had no idea it was missing because the instructions don’t mention it

I literally just told Tom that instructions are only for when stuff goes wrong lol.

it will be a little bit easier to get the black goo from the frame in the fuel system with the filters off. I just ordered one and a PPE oil pan

I've pre ordered mine. Hope it doesn't take too long to get it.

Interesting stock fuel filter setup. I'm actually surprised, I just did the fuel filters on my Canyon and it has two, not just one, in the housing. That said, this looks like an amazing upgrade that I'll have to do to my new truck at some point.

I just carry extra filters and my socket wrench in case I’m on the road and need to change out filters. This seems like a good idea….. but the question is…does this void the warranty….?

Update: after installing the forward Donaldson filter sprayed fuel. Replaced with a Napa PN 3626 with sealed correctly.

Enjoyed the video, don’t sweat the extension 90% of the vehicles on the road probably have a 10mm socket stowed away on them somewhere lol. Do you have an affiliate link for the VSE gear you have shown in the last few months?

On more question, what would be the filter change interval? I idle a lot during the summer so would I have to change it based on engine hours? Also will the fuel filter guage on the truck still be accurate?

Great video! Helped a lot replacing my OEM with a new OEM. I was a dumbass installing a new filter and had to replace the whole thing. Thanks again for the video

I bought a 2021 with the 3.0. It was eating 2 qts of oil every 1000 miles. After a year of oil consumption checks every 1000 miles they decided to change out a valve cover with a bad baffle inside. The oil eating went away and it was back to being a "good truck". But that's when the next batch of problems started. Spraying coolant out of the inter cooler, leaking oil, a particulate filter that's so clogged that it backs up exhaust smoke into the cab while driving. They have had my truck in and out of the shop coming up on 8 months now. GMC is not willing to buy my truck back.

Thank you

Nice install, but you lose the protective shroud. I know you don’t keep vehicles for long and warranty isn’t an issue for you, but how might this affect a typical owner and warranty issues that might arise? But I really like the idea of double and higher quality filtration, especially here in illinois where I hear our diesel is the crappiest.

Nice video. I have an LM2 but see they have a kit for it also... Just wondering ...towards the end of your video after you check for leaks you show a view of the kit looking straight in on the kit. Not so worried about the filters maybe being a little lower than the bottom of the frame rail but it looks like the top of the conductivity probe housing and the fuel outlet block are a good bit closer to the bottom of the cab. May not be but looks that way. Hopefully there is enough clearance to allow for any cab movement.

After putting almost 100,000 miles on my 2021 3.0l and all the time it has been in the shop I’ll be going gas 3/4 ton or 1 ton with out cylinder deactivation

Do you feel like this install is necessary? Or just replacing the plastic cover with a metal cover so you don't round off the plastic nut and running a k&n filter is just as good? Thank you for all the videos!

I assume now that you'll replace both filters now at the same time going forward? Considering this truck and just researching as this would be my first diesel. I wonder what other filters from other mfgs are available if Donaldson discontinues those? I'm glad to see that its not hard to prime the diesel fuel system yourself now so this can be done in the garage. Thanks for the video.

Your video should make the transfer from the factory setup to VSE's much simpler. Thank you. I have one on order. I have never felt the factory setup was sufficient. I have a question about your secondary filter. The literature shows a Donaldson P551315 or a Cat 1R-0751. The filter I see installed on your unit is a Donaldson P550638. Please clarify.

can these install on Isuzu Dmax?

Does the double filtration, specifically the lower micron filters, add pressure loss into the fuel system? My worry is that the pump isn’t made to handle that type of pressure drop in the system.

Also broke one of the Blue snaps for the quick connect fitting. The VSE instructions call it a “security clip”. Any Idea what the GM part number is so I can replace it?

My wife and I use puppy pads but for a much different reason. 😉

Is the post fuel filter (after the water separater) supposed to have an o ring? My system is leaking from the post fuel filter a decent amount and I’m pretty sure I tightened it enough but maybe not. Just really looking for an answer…

How often does the filter need to be changed? Looking at a LZO

You have several videos comparing 3.0 Oem fuel filter. Is VSE Fuel Saver not preferred or stay with Oem filter.

With the dual filtration : what is the change interval if normal driving occurs (non extreme environment) Factory suggested was 30K

Followed your instructions and still getting leaks looks like from the top of the unit any suggestions?

I know my wife didn't use the factory nuts. I got a DNA test.

Do you happen to have the part number for the blue safety clip?

Quick question that little hose with the wire connection to the right of the filters, it that the fuel pressure sensor?

Does this brand happen to make this for a 2.8L? My Colorado zr2 bison from the factory comes with duel cartridge style ACdeco filters everything on the truck is stock……for now!

This seems like a cool product but I can't imagine how they can justify 500$ for the machining of this part and a couple filters. I would probably be a buyer at around 150 to 200 tops.

I have the 1500 silverado duramax wheer you locate oh more information for buy you product

why are extensions always to long and the other too short.

These trucks make lots of weird noises when you shut them down.

Could you remove the housing without removing the stock filter first?

Any issues with the Donaldson filters leaking? VSE has since switched to Baldwin filters due to the Donaldson O-rings not being up to snuff.

Will this void any factory warranty on the vehicle?

Surprised there’s no skid plate to protect it

So does this basically just filter the fuel twice?

Thanks for turning us onto the VSE Fuel System Saver! PS: I’m assuming that you’d like your RU-vid channel to have long term success. Please take some editing classes, or tips, from channels like Savagegeese, or KYD. ✂️🎞️✨

This is awesome as my 22 refresh lm2 already had an entire fuel system replacement due to metal In the system. I need to ask though , will it void my warranty?

Does this void warranty?

can you go over change intervals? I tried to see if I could find something but no luck.

Here’s a question I have, when you do a fuel filter change will the fuel filter spew all over the place without having that drain valve?

Does this work for the lm2

Would this work for the 3.0 in the Tahoe ?

Dose any of this void the warranty?????

Be honest, do you smoke weed?🤣
