If water or sediment is found in the BEAR Power Unit primary fuel water separators during the daily inspection personnel would

• A. Remove all contaminants to prevent damage to fuel system components
• B. Drain the fuel tank
• C. Replace separators
• D. Ignore

Answer: (C)

Contaminant control in the fuel system relies on a disposable primary fuel water separator. When water or sediment is found during daily inspection, the separator has become saturated and can no longer effectively remove moisture and particulates. Replacing the separators restores full filtration capability, keeping water and dirt from reaching the fuel pump and injectors and protecting components from corrosion, wear, and potential failure. Draining would not remove contaminants trapped in the filter medium, and simply ignoring the issue could lead to engine damage. Replacing the separator is the proper maintenance action to maintain clean fuel and reliable operation.
