Fuel is the main food of an engine. Stronger the engine, the higher amount of fuel that it needs. But a lot of incomplete combustion and circulation happens in the engine that causes the fuel to become dirty.
Dirty fuel will slow down any kind of engine – even the mighty Chevy Duramax. It may be one of the most reliable engines out there, but in order to get the longest use out of it, you will have to add a fuel filter to it.
We are sure that you don’t want to put anything but the best Duramax fuel filter inside this engine. So, let’s take a look at some of those options below.
5 Best Duramax Fuel Filter Reviews 2023
There are many filters available in the market. But here, you won’t find all of them; you’ll only find the ones that are worth your time and money. So check them out below to avoid further confusion!
1. GM Genuine Parts TP3018 Fuel Filter with Seals
GM is a big name in the automotive world. They come with years of experience and expertise in the field. So when you get a fuel filter like this one from them, we don’t think much room for doubt is left.
This TP3018 is a fuel filter that comes with the best innovation from GM. Installation and compatibility issues will go out the window because this is made to the original blueprint of the GM vehicles and engines, and so it will fit right into the interior.
This filter can handle all kinds of contaminants. Dust, paint particles, and rust will never clog up the fuel tank if the oil is allowed to pass through this filter. Due to the ACDelco professional advantage, this engine will filter out all the contaminants of the fuel before they enter the delivery system.
There is no water separator in the filter – it will only work to pull out oil contaminants. If you want to run your engine on the stock fuel system, then this is the filter for you.
The filter on the outside is a bit rough and will stop thicker particles on their tracks. But inside it is a fine micron filter that will stop the finer particles from getting through. So with this double-layered filter, the fuel will get cleaned through and through.
2. iFJF 12642623 Fuel Filter Head for Duramax Fuel Filter Housing 6.6 Replacement for GM Chevrolet GMC Duramax V8
This is a complete, all-encompassing filter set that is going to clean up the fuel for you to make your engine super smooth and efficient. The filter kit includes a fuel filter and a filter head. There is also a sensor that indicates the level of accumulates that have gathered up in the filter screen.
If you have a Duramax 6.6 liter Silverado or a Sierra Chevy, then this will be a perfect match without needing any modification. On the other hand, there are models from the year 2001 – 2004 that will also work with this filter after you get it slightly modified.
The micron level of the inner filter is 5, and the filter inside is multi-layered. The fuel will go through several degrees of screening before finally reaching the main feeding station of the engine. The separation also takes water out of the fuel, and it will do so to a max efficiency of 98%.
The filter comes thus with such high efficiency. But another thing that makes it stand out is that it has a billet body made with aluminum. On top of being made with this highly non-corrosive metal, the filter head has been passed through the process of electrophoresis, which further prevents rust or any sort of decay to the body.
This filter is also pretty simple to clean – you can thread it out and clean it regularly whenever the filtrates start to accumulate under.
What helps the cleaning process is the fine threading around the bleeder screw on the filter’s head – unlike cheap threading designs, this one will not become worn out and so you are going to have no trouble with screwing and unscrewing this head.
3. WIX Filters – 33960 Heavy Duty Spin-On Fuel Water Separator, Pack of 1
This is a spin-on metal fuel filter that comes with a water separator along with the fuel filtering screens. If you are looking for a filter that will be finer than the ones we had been talking about, this is one to go for.
It has a heavy-duty body made with durable plastic. You might have some concerns with the plastic, but in reality, the quality and thickness of the plastic used here makes it way better, way more durable, and much more affordable than metal ones.
The installation of this filter head will take only about 15 minutes.
When installing it, you will be surprised at how perfectly it will sit into the uppermost compartment of the engine. The reason for this is that the corner lengths of the filter’s body have been tapered to a slightly slanting angle. This gives its body more heft and stability so that it is less susceptible to damage.
One of the main problems with filters is that they leak. Not this one, though. You will find this plastic to be much more reliable in terms of fuel-water separation as well as with the fuel separation.
4. XDP Duramax CAT Adapter with 1R-0750, Bleeder Screw & Spacer
This is an excellent filter for Duramax engines. It has a very tough and rigid body made with thick anodized aluminum. The metal itself is already resistant to corrosion. And the anodization on the top layer just makes it all the more resistant to any rust attacks caused by moisture.
The filter adapter threads right into the head of the OEM filter and fits tightly in place. You don’t have to fear leaks with this filter at all. You will have great clearance for whenever you want to remove and clean up the filter. Two extra accessories – an extra bleeder screw and a bleeder spacer will be provided in the kit in case any damage comes on the threads.
This is a perfect fit for most Duramax filters. The only ones it will not be a good fit for are the LML and L5P trucks because their fuel tank is longer.
You can run the car for about 200,000 miles and not have the filter sensor light beep up once.
This is a very affordable, trusted, and reliable filter – you are not going to regret buying this for your truck as the mileage and the fuel economy will greatly be enhanced by many degrees after this filter has been installed.
5. ACDelco TP1015 Professional Fuel Filter with Seals
This is an original ACDelco from General Motors, and thus it will be a good fit for Duramax engines in general.
However, this will not be compatible with every type of Duramax. For maintaining the right neatness and quality of the filtration, this should only be applied if you have a Duramax that was made after 2017.
It will only take about 10-15 minutes to thread it into the engine compartment. O-rings will be provided in the kit, and the canister will also sit well adjusted into the engine folds.
The micron level of this filter is just right – there will be no clogging until about 20,000 miles in the least. Moreover, GM recommends using this for their Duramax engines for the best cleaning on the fuel.
Buying Guide For Duramax Fuel Filter
The fuel filter is vital for keeping fuel clean so that your vehicle runs efficiently. If you are going to buy one, then you have to know some details about it otherwise you’ll just be at a loss about what to look for. Don’t worry, in this section; we’ll help you to know it all.
Quality of the Filter Body
The fitler must come with a body that you can depend on. It must be stable and strong enough to last you a long time. Fuel filters are always exposed to corrosive agents, and so it’s very important that these filters are made with something that will not be affected by the burn caused by the corrosive agents.
The material with which the most durable filters are made is aluminum.
So, we will advise you to get an aluminum filter over all the other options you have. The primary property which makes aluminum a good choice for fuel filters is their resistance to corrosion. The naturally forming layer of oxide on aluminum helps to shield it from the surrounding moisture and thus helps to prolong its life.
There are other useful properties of aluminum that make it suitable for these filters. Aluminum is very ductile, lightweight, non-magnetic, and impenetrable. They are also recyclable – so you will be able to properly dispose of them once you’re done with them.
There are other options apart from aluminum.
You will also get a larger variety of corrosion-preventive measures in the form of externally applied processes like electrophoresis, anodization, or painting.
Whatever the method is, you must, first and foremost, choose a filter that’s been made with a material that can properly balance out corrosive dangers.
The bad thing about filters is that there is no universal size that fits all. If your stock filter has been damaged and you need a replacement, then you will need to get into the specifics of the fuel filter to find out which one suits you best.
A filter that is not compatible with your vehicle will never give you sufficient results.
Another way to check whether the filter will be compatible is to find out whether the in-line diameters are a good fit with your vehicle’s fuel line.
After you are sure that you have found a compatible filter, make sure that the threads line up properly with your stock fuel filter.
This is the most important aspect of a filter. It is a measure of the size of particles that will get held up within the filter screen. The smaller the micron permeability, the cleaner your fuel will stay.
To get a better measure of this, let’s make some comparisons.
Fine sand is of the biggest size – it is 250 microns. Each salt grain is of 60 microns, silt is about 44, waste from dust mites has particles of 20 microns, and finally, the smallest particle size is that of pollen, which basically has 15 microns for each individual grain.
The best micron permeability level for a filter is about 5 microns or lower than that. These filters will catch all the particulates we mentioned and more. Note that such a fine filter will surely get filled up more easily and thus will need to be replaced sooner than those that come with higher permeability.
However, it will be worth the effort because your engine will get better fuel sustenance.
FAQs About Duramax Fuel Filter

If you see that the power of the car drops when you’re going uphill or accelerating, then that is probably happening because the filter has become clogged with too many impurities.
2. How frequently should a filter be changed in a diesel truck?
Ans: The best thing for you to do is to get a new filter after your car has covered every 10,000 to 25,000 miles.
3. Is it necessary to change filters?
Ans: Of course, it is necessary. Getting clean filters helps the engine to stay healthy.
4. How much permeability will be best for the filter?
Ans: The optimum level of cleaning can be gotten from filters that have a permeability of about 5-10 levels of a micron. This one will filter out all the impurities without getting clogged up too much.
