Q: What can be done to protect against water in fuel?
A: The two main methods used to combat water in diesel fuel are emulsifiers and demulsifiers. There are pros and cons for each method, but we feel that demulsifying or separating out the water from the fuel is safest for the fuel system. Modern fuel systems are equipped to catch water safely before the injection system. If an emulsifier additive is used it is possible that an unsafe amount of water could pass through the filter and into the injection system. We have heard of injector tips breaking off and falling into the combustion chamber because water was in the fuel system at unsafe levels. A demulsifier eliminates this risk and usually lowers the freeze point so the moisture doesn’t freeze.
