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?
