It is designed to strip water and solid contaminants, like rust and dirt, out of diesel fuel down to 30 microns at 95% efficiency before they reach sensitive injection pumps and injectors. By keeping the fuel system clean and dry, it helps prevent corrosion, injector tip damage, and engine misfires. Replace this filter at manufacturer-specified service intervals or when a dashboard water-in-fuel light appears to avoid expensive fuel system repairs.
