Contaminated Fuel – What happens when water gets in your diesel tank?

Although modern Diesel fuel injection systems have less moving parts than traditional mechanical systems they are more prone to damage due to the much smaller manufacturing tolerances.

Since Diesel fuel injection systems were first invented and used to control engine operation, water in the Diesel fuel has been the biggest contributor to the failure of such systems. Repairs are generally expensive due to the hi-tech nature of components and the amount of parts that can be affected by the contamination.
