Why do Common Rail injectors fail?
Why do Common Rail injectors fail?
Water contamination: Another common cause of Common Rail injector failure is contamination from excess water in the fuel. If not stored or handled correctly, water can enter the fuel and will react with the chemicals in it to corrode metal surfaces and reduce lubrication between the moving parts.
