The 3 Types Of Diesel Truck Fuel Filters

oday’s diesel truck drivers encounter all kinds of environmental challenges while on the road. You can have contaminants, allergens and other seasonal troubles in your vehicle even if you keep your windows closed.

Properly maintained diesel truck fuel filters help prevent diesel contaminant from entering your engine. They also benefit both drivers and trucks by providing a barrier for these contaminants from entering the vehicle. This help prolong your truck lifespan as well.

In this post, you will learn about the common type of diesel truck fuel filters that are on the road today.

Diesel Oil Filters

Diesel oil filters are standard for any truck that runs on diesel and require oil to lubricate the pistons in its engine. The oil filter will help keep the engine clean and more efficient by removing used oil from the engine.

A diesel engine needs more oil to operate efficiently than a gasoline engine. This is why you’ll have to replace or change your truck’s oil filter more frequently than a passenger car.

Diesel Particulate Air Filters

Diesel fuel contains a certain amount of particulate matter (particulates) formed as byproducts of combustion when diesel fuel is burned. With a diesel particulate filter, you can keep up to 85% of the particulates, hydrocarbons, and higher levels of carbon monoxide that circulate through the engine.

A diesel particulate air filter removes particulates from the engine and helps reduce the level of smog and dirt in the air and reduce your emissions, which in some states is a necessary and required part of diesel truck ownership.

Keep your truck’s air filter clean by checking it about twice a year or more often if you use your truck for a lot of heavy hauling jobs.

Diesel Truck Fuel Filters

Diesel fuel filters are specially designed to keep diesel from being contaminated. These filters help clean the fuel before it is sent to the engine.

The diesel fuel filter keeps larger particles of paraffin from entering the engine while allowing water to be extracted and let drain.

The heater inside the filter continuously melts paraffin (a kind of wax that can clog your engine’s valves) to prevent fuel clogs, and then the melted paraffin passes through a special fuel filter.

Your engine valves get clogged up. This causes your engine to not run properly, or it may grind when you shift gears. This is an indication that its time to change your diesel fuel filters.

Like the other two types of filters, you should check the diesel fuel filter and replace it when it’s getting dark brown, greasy and/or black and sticky.

What Micron Should A Diesel Fuel Filter Be?

If you are wondering or reading about what micron diesel fuel filter you need, below are suggestion that you can consider.

The role of the primary filter is to removes contaminants from the intake air that comes through the air cleaner. The smaller filter may be fitted after, or even inside, the larger filter. When choosing a primary fuel filter, make sure that it will remove particles that are less than 0.004″ or 10 to 15 microns.

The secondary diesel fuel filter is the second filtration device that your boat’s fuel will pass through. This equipment should be installed after the primary fuel filter and as close to the engine as possible to avoid contaminating the second filter.

Most secondary and final filters are designed to remove particles ranging from 0.00008″ to 0.0001″ or 3 to 5 microns.
