The problem I see is that the primary water separator on the VSE has the conductivity sensor on the clean interior side of the filter and by the time you get an alarm the filter exterior will likely be close to full of water. Typical commercial equipment that uses these filters that are water separator has a separate water sensor.

Great video! I would rather be safe than sorry, so I will be upgrade shortly.

I installed the vse on my 22l5p definitely a worthy upgrade the cat 1r 0750 fits just watch the seal some are defective and don’t seal

I’d say the whole point is to not need these, until you do, which is unpredictable. I’d hate to wish I would have had them after it is too late!

I replaced my stock filter with another OEM filter at 10,000 miles. The used filter looked perfectly fine and no water. The only way to see 10 micron particles would be to place the paper element under a microscope. I’ll stick with the OEM filter system at least until the warranty expires.

I think this means, you don’t need the dual filter set up. The factory fuel filter set up is efficient enough. I’m not adding nothing to my LM2, until after it’s paid off. The truck still belongs to the bank, make extra payments versus adding aftermarket parts imo.

I had a CAT 1R-749 gets severely clogged at 16000km after one stop at rural diesel station. I was suspecious of the fuel so i just filled 20 liter only thinking it wont harm much and boy i was wrong!!! Car started to stutter hard. At least it saved my injectors and the injection pump. I cutted it open and you can see it in my channel it was clogged entirely. Come to think of it it was upgrade well spent!

Hey I have the same system runner for 2024 LZ0 and the CAT fuel filter is 1R-0751 not 0750 and I don’t think there is a CAT fuel water separator. Jim M

It would be interesting to see what color the media started out as. If the darkening of the factory filter corresponds to how much garbage it traps, it would make sense that these filters spread that out over a larger surface area and don't look as dirty. My big question about this setup is still the placement of the water in fuel sensor. The water would collect on the dirty side of the separator unit, but the sensor is on the clean side and has no way of sensing what's going on with the dirty side. If the separator fills with water to the point that water is passing through the media and reaching the sensor, then it's already headed upstream (I don't think that the secondary filter is able to separate water). That being said, I've had my LM2 for two years and 35,000 miles and have never had a water in fuel issue (knock on wood), so either A) water in fuel isn't as prevalent as it used to be, or B) the factory sensor gums up with debris and doesn't detect small amounts of water in the first place. Either way, the finer filtration seems like a bigger issue and more than enough of a reason to run this setup.

I’d say no news is good news. Your probably purchasing diesel from a reputable retailer who keeps up on their filters as well. Just watched a video from I Do Cars where they tore down a 2020 LM2 due to what appears oil starvation to #6 rod bearing or possibly a turbo bearing seal/failure. Curious if you’ve seen that and your thoughts.

I see that you left information on the CAT filter but not the CAT water separator. Do you have that information? 🤔

Any concern with regards to the additional length of the Cat filters where they may be more susceptible to being hit by road debris. Appears the factory filter is tucked up in the frame a bit more than the aftermarket filters.

What are part numbers for the correct CAT filter and water separator?

Does the fuel from the tank go into the interior side of the water filter or go to the exterior side on this setup? The spin on filters are usually designed so the dirty side is the exterior side and the water sensor is on the inside. Just wondering how the water sensor is picking up the water level inside the filter if the water happens to be on the exterior. I see FASS systems has retained the original Chev design filter on their version of this so that the water sensor still functions.

Thanks for the review. I have this on my 2021 LM2 Duramax. What is the part number for the Cat water separator filter?

Looks like over kill for your application , now if you had primarily got your fuel from an old farmers tank , i can see the justification .

was the first factory filter the one you cut open and how many miles

Does this set up negate your warranty?

What’s the part number on the CAT water separator. I didn’t think the Caterpillar water seperators worked with this system

theres find dirt in it its discolored

Looks like a waste of money…3.0 Duramax has been tested up to 2.5 million miles with OEM parts.

Use a microscope. Your looking for VERY small particles.
