Best Duramax Fuel Filters for your Car (Reviews & Buying Guide by Professional Tuners)

One of the most important elements of the internal combustion engine is the fuel filter. If it operates correctly, the whole car functions well. Prevention of the abrasive resins and impurities penetration is one of the main tasks the filter has to do. Those things are formed because of the chemical reactions in the combustion chamber and fuel line. Nevertheless, there is a high paraffin content in diesel fuel, which becomes crystallized when the temperatures are negative. Therefore, it is very dangerous for an engine if those particles hit it.

For instance, if the fuel filter is of low-quality, it retains water poorly so that the water leaks through them easily. After that, it comes to injection system together with the fuel. Therefore, it disturbs the combustion process of the mixture, making the corrosion appear. This is due to the fact that even a little amount of water leads to the damages of the injection system. Consequently, it is necessary to have a filter of high quality. To help you, we prepared a list of top 5 best Duramax fuel filters to check out. Ready to review?

Buyer’s Guide to Choose the Best Filter

The signs when you have to change the fuel filter:

• The engine power is reduced
• There is an increase in fuel consumption
• When you are going uphills, the vehicle twitches
• The car begins braking itself
• The acceleration is poor
• The engine stalls or stumbles
• When you begin to drive, the power unit of your vehicle’s engine begins to vibrate. Also, there is a loss of power in the engine

Things you have to pay attention to when buying a filter:

1. Manufacturers: Choose the one that offers the best quality.
2. Cost: Do not look only for filters with the lowest price because sometimes it is better to pay more, but be sure that the quality is good. However, note that sometimes there may be discounts, even for very quality products.
3. Overall look: You’ll have to find the code, either stamping or engraved, product number, and also the logo.
4. Design and Packaging: If the manufacturer is serious, the packaging will be solid as well. There must be a logo and high-quality seal. The design should be striking and exclusive, ensuring the product is not a fake. Also, if the filter is of high quality, the metal procession should be solid so that there will not be any scratches, burrs, or chips.
5. Gaskets: The gaskets are to be of high quality. Otherwise, if the product is fake, there won’t be any gaskets.
6. Nice quality: Of course, a good filter should be made of rigid and dense material so that the quality is solid. All the parts inside the filter should be well-glued or assembled.
7. Filtration Subtlety: This is such a parameter which determines the fraction size, which is guaranteed to be retained when you insert the filter. If it is a gasoline vehicle, the value is 10 microns, and if it is a diesel vehicle, the value is 5 microns.
8. The guaranteed purification degree: This is a parameter, which is displaying the number of elements the filter is possible to hold. It is measured in percent. For example, if the model of a filter is very good, such parameter would be 98-99%.

When you are selecting the filter, it is recommended to concentrate on the technical parameters and engine brand. For instance, you would better focus on such things as internal and external diameter, diameters of outlet and also inlet connections, and the body frame dimensions. Besides, pay your attention to the filter’s completeness. To be more precise, the vast majority of manufacturers are adding O-rings that are not superfluous totally, when you are replacing the filter.

The structure of fuel filters for diesel engines is complicated. For example, the filter should retain the water, but it is prohibited to let it into the combustion chamber.

The diesel engine is rather sensitive, regarding the degree of the purification and quality of the fuel mixture.

In general, there are 3 stages of purification of diesel fuel: in a tank, in a primary fuel filter, and also in a fine filter.

The vast majority of manufacturers claim that you should change the filter after each 30 thousand kilometers. However, we should do it more often if the filters are made with plastic. It is to be mentioned that if the quality of a filter is not good, you would rather change the filter more often. Also, you need to do it, if the vehicle lost its agility and power and there was a dramatic increase in fuel consumption. Choosing the filter, do pay attention to such characteristics as heating element power, permissible pressure, filtration quality, capacity, and dimensions.

Is important to purchase high quality filter. Otherwise, you will face these problems:

• With poor filter paper quality there might be micro-contaminants separation, getting into the pump, and then to the engine’s injectors with fuel
• With coarse filtering material, trapping of the little impurities will be impossible and also little particles will pass through
• With low absorption capacity, filters might become clogged soon. Within short period of time, they will need to be replaced more frequently
• With clogged filter, the fuel run would be prevented from getting. Hence, you won’t even be able to start a car
• With too loose winding, the quality of the filter would be reduced to almost zero
• With torn fuel material, the fuel would become almost raw and then even be getting to the injection system
