Diesel Fuel Filters

A diesel fuel filter operates in a fundamentally different way from the rest of the common categories of filters. The diesel fuel itself is more prone and conducive to a filtered system, but this system gathers more particulates and expresses them into the body of the fuel, so that they may be burned off. The common method to remove the carbon particulates is to use extra fuel from the engine to burn it off intermittently. The burning of these particulates reduces the carbon footprint of the exhaust system by limiting what the engine actually exudes.

The diesel fuel filters also propose a problem in cold weather. Because of the consistency of the fuel that is used, it is prone to waxing or gelling in extreme circumstances. The point is that the weather gets too cold for the proper flowing of the diesel fuel, and it begins to crystallize into a more viscous form. This is a problem because it can cause buildups in the fuel line as well as at the filter. The problem is remediated by two methods. One is that you ad coiled electronic heating elements to the entire fuel line assembly. The other is that you begin to mix the diesel with other fuels, such as kerosene and this is common in extremely cold near-arctic and sub arctic conditions. Additionally a spill return system from the engine, where excess fuel is returned to the tank, can help contribute to a higher overall tank temperature, thereby preventing gelling.
