A high-quality final fuel filter is vital for protecting advanced| high-pressure systems and allowing your engine to run at peak performance. Modern diesel engines are fitted with advanced high-pressure| electronically controlled injection systems. These engines are designed to provide significant improvements in combustion efficiency| power and economy| running at extremely high pressure and very close tolerances. However| advancement comes with a price: modern systems are susceptible to damage| as a result of poor-quality fuel and more commonly| contaminated fuel. Whether it be water or particles that pass through| repairing damage due to contamination can be truly expensive! One way to give yourself peace of mind is to add heavy-duty protection to your common rail diesel. Diesel Dog has the answer.
