How to Choose The Perfect Duramax Fuel Filter

When you are choosing the best filter for your duramax vehicle consider the following things about the filters you have to choose from.

Filter Element of Complete Housing

Some fuel filters are designed to be completely changed when you change them. This means the entire housing needs to be replaced when you change your fuel filter. Of course changing a complete housing is more work and it is more costly than changing a filtration element.

Other fuel filters provide you with a replaceable filtration element that fits into the housing you already have installed. These filters cost less because there are fewer components. They are easier to change, and they are usually made of the same high quality filter media that the other filters are made of.

Your vehicle manufacturer may recommend the fuel filter you use be 18/16/13. That means that the filter would eliminate specific numbers of contaminants that measure 6, 6 or 14 microns.

The 18 represents a filtration of 2,500 particles that measure larger than 4 microns while the 16 represents a filtration of at least 640 particles that are larger than 6 microns. The final number of 13 represents filtration that can remove 80 particles that measure 14 microns or larger.

These calculations are designed for each milliliter or fuel cleansed by the filter. No human eye would ever be able to see particles of this size without the help of a microscope.


You want to get a filter that is going to protect you from as many contaminants as possible. The fuel filter ability to stop certain sizes of particles from entering your fuel system is measured in microns.

If a fuel filter is labeled as 3 microns then it will be effective at stopping particles or contaminants that are 3 microns or larger in size. If the fuel filter is labeled as 5 microns then it will stop particles that are 5 microns or larger.


The materials that are used to craft the filtration element are referred to as media. There are cellulose media, and glass fiber media’s available. The glass fibers are uniform in size and diameter where the cellulose fibers are not uniform.

The glass fibers are smaller and capable of trapping more particles and finer particles than the larger cellulose fibers can. When you choose a filter element make sure that the media the element is crafted from will be able to catch the most contaminants.

Metal or Plastic Components

The cap and housing elements for a fuel filter can be made of plastic or metal. Choose the filter that is made of the most durable materials so you will not have to change them as often.

Final Thoughts 

Your first consideration with a fuel filter, or any other filter on your vehicle; must be whether the filter will void your manufacturer warranty or not. Always check your warranty details prior to changing the filter type that is on the vehicle.

Once you decide to change the filter type then make certain that you get a filter that is the exact same size as the original filter so you will get a precise fit. If your filter does not fit exactly like the original equipment there is a possibility of leakage.
