The main cause of damage to the fuel system of diesel engine ?
The primary cause of diesel fuel system damage is contamination.Water:Causes corrosion(rust), microbial growth(slime), and injector failure due to steam expansion. Particulates: Dirt and grit cause abrasive wear on high-pressure components and clog fuel flow. Air: Leads to cavitation, which erodes and pits the internal surfaces of the fuel pump.Prevention: Use high-quality fuel, replace filters regularly, and drain water separators frequently.
