Changed at manufacturer-recommended intervals, A Mercury fuel water separator is a device that works to ensure clean fuel is delivered to the engine.

Properly speaking, a Mercury fuel water separator is a small filtering device used to remove the water from the diesel fuel before it reaches to the sensitive parts of the engine. The Mercury Fuel Water separator acts as an added line of defence for your vehicle's fuel system, filtering water and particulates from the fuel before it reaches the fuel filter, ensuring only a flow of clean fuel reaches your engine. A Mercury water separating fuel filter is designed to catch the impurities or water before they reach your engine. The principle behind this filtration system is surprisingly simple; the top of the filter consists of a paper element and the bottom of the filter is a holding tank or bowl. Mercury fuel-water separating filters for all common engine models are available at PartsVu.
