2001-2010 Duramax
The common rail injection system used on all Duramax engines from 2001-2010 allowed General Motors to literally double the power output and fuel economy over the older 6.5 diesel engine. There is no doubt, whatever version of the Duramax you own, it is often considered the best diesel engine ever produced. If you do own one, you may have already replaced the injectors, or at least heard about how bad the injectors can be and how expensive they are to change. This is a very common misconception. There is nothing wrong with the injectors themselves. The problem is with the GM fuel supply system and filtration. Isuzu originally designed the Duramax engine and joined efforts with GM at their Moraine, Ohio assembly plant. So yes, the engine was originally built by Isuzu, but it is in fact assembled in the US by GM technicians.
When Isuzu designed the engine, they went with the Bosch injectors and injection pump because of Bosch’s unsurpassed quality of products. The thing that causes the injector failures is not Bosch’s fault, nor Isuzu’s fault. GM did not take into consideration that the Bosch injectors require a minimum of 4-microns of filtration. When GM produced fuel filters to accommodate the Duramax engine and Bosch fuel system, they used a 7 micron fuel filter. So right from the start you are allowing particles almost 2 times larger than the injector can even handle to pass through them. The #1 cause of injector failure in all common rail engines is poor filtration, not bad injector design.
The second thing GM failed to design properly is the fuel supply itself up to the CP3 injection pump. There is none……..
We're not sure how GM thought this was going to be a good idea. The Dodge Cummins common rail uses the same style CP3 injection pump as the Duramax engine and very similar injectors, but Dodge uses a lift pump in the tank to push the fuel up to the CP3. This mean the CP3 only has to do the job it was designed to do, and that is feed the injectors with high pressure fuel. Since GM didn’t use a lift pump, the CP3 is trying to not only keep both fuel rails and all 8 injectors pressurized and happy, but it is also trying to pull fuel from 10-15 feet away in the tank to keep itself full of fuel. This causes a lot of excessive wear on the CP3 and the entire injection system. As the CP3 begins to wear, it starts to cavitate under throttle. Cavitation is when the fuel isn’t being pulled or pushed in the proper volume to keep all the fuel lines full and the fuel becomes aerated. When air enters the fuel system it immediately causes irreparable damage.
Why We Put Fleetguard Filters In Our Kits
We developed these kits years ago to give guys the BEST protection they could get for their trucks at an affordable price. We also wanted guys to be able to get filters in there local hometown, rather than buying them from us like other companies do. We had the CAT 1R-0750 filter in our kits for over 10 years, because they are a great filter and are readily available. Now the CAT filters are considered an older filter-media technology compared to the advancement in filtration over the last several years. We have also seen fake knockoffs out there in the marketplace that can cause issues and leave you less protected. Our goal will always be to provide you with the BEST filtration you can get, to protect your high-dollar investment. Introducing the NanoNet technology!
The newer NanoNet technology found in Fleetguard fuel filters is now the most up to date, advanced technology and superior protection you can buy. The result of this Nanonet technology gives it a 2 micron rating at over 99.6% efficiency! Do your own research on these Fleetguard Nanonet filters. For the low cost and the easy availability, you will be pressed to find a better filter out there to protect your truck..
What does this mean to you? It means our kit, and a simple 60-90 minute install can save you thousands of dollars in repair costs on your Duramax truck.
"It's very cheap insurance to protect your high-dollar investment....."
*We have complete kits for the 2001-2010 Duramax diesel consisting of eveything you will need to protect your wallet and your truck from this possible premature failure.
Both kits are described below.
Our Duramax Dual-Filter Kit is for both better fuel and water filtration and is an inside-the-frame mounted nice and tight up under the cab. This kit requires NO drilling or welding. You simply bolt this on to the frame rail using existing factory holes, connect the 1/2" hoses to your stock fuel line using the supplied fittings and provide simple 12 volt power to the pump. The kit includes the pump, filter bases, mounting bracket, Fleetguard FS1212 water separator, FF5814 Fleetguard fuel filter, hoses, fittings, mounting hardware, mini tube-cutter and full-color detailed instructions. The installation is very straight-forward and takes approximately 60-90 minutes to complete. The bracket is laser cut 3/16" steel and comes in a black, double powder-coated finish.
Our Duramax Single-Filter Kit is an inside-the-frame mounted nice and tight up under the cab. This kit requires NO drilling or welding. You simply bolt this on to the frame rail using existing factory holes, connect the 1/2" hoses to your stock fuel line using the supplied fittings and provide simple 12 volt power to the pump. This kit is mainly for guys that have already installed an aftermarket secondary fuel filter where the stock filter goes and just want the pump and water separation. Remember, the CAT filter you installed does NOT separate water! The kit includes the pump, filter base, mounting bracket, Fleetguard FS1212 water separator, hoses, fittings, mounting hardware, mini tube-cutter and full-color detailed instructions. The installation is very straight-forward and takes approximately 60-90 minutes to complete. The bracket is laser cut 3/16" steel and comes in a black, double powder-coated finish.
Pump Information
We designed this anodized pump head to our specifications to fit an already very popular motor/impeller that was out there on the market. These pumps are not cheap to produce, but do exactly what we need them to do by simply pulling/pushing the fuel through the filters and parking it right at the mouth of the CP3 injection pump waiting for use with positive line pressure instead of a vacuum pull from the tank. This is very important on the Duramax because not only does the CP3 have to provide the high pressure to the fuel rail, it also has to do the job of sucking fuel from 18 feet away where other manufactures push the fuel from inside the fuel tank up to the injector pump which is a much better design. This overworking the CP3 produces unneeded wear over time and allows harmful air bubbles into the fuel system from cavitation. The pump is a centrifugal design and is super quiet (less than 40db) because of the magnetically-driven based polyphenylene oxide impeller that sits on a ceramic ball bearing inside. It offers many benefits over other pump styles out there because the magnetic motor eliminates impeller slippage, it does not have a shaft, which means it has no moving internal parts to wear out and is a brushless design. This combination makes the pump a total flow-through design if it would ever fail, but also gives it a life expectancy of 50,000 hours use on a 12 volt system.
The filters for both kits are very affordable ($15-25) and are readily available locally or online. No filters you have to buy from the place you bought the kit.
* We do also offer the Fleetguard FS1212 water-separator filter in our Single-Filter Kit if you already have a secondary CAT fuel filter installed.*
A Common Rail injection system is very sensitive to any contaminants, which is why better fuel filtration is so important in promoting long, healthy injector and fuel system life. The current refined diesel fuel, is not clean enough for these high-pressure injection systems. Along with our kits, we recommend that you leave the stock fuel filter installed. We also recommend the use of a good, high-quality diesel fuel additive with each fill-up to further protect your complete fuel system and give it the proper lubrication needed. An easy to find one nationwide at any auto parts store is either Stanadyne or Power Service.

The Single-Filter Kit is the same as the Dual-Filter Kit above except only contains the Fleetguard FS1212 water separator. It's for you guys that are already running a better aftermarket filter in your stock location and need water separation and a pump to relieve stress off of the CP3. Remember, if you are currently running just a CAT filter alone, you are not getting ANY protection from water in your fuel system. This is a very important part of a reliable fuel system, and no headaches down the road.
