FUEL/WATER SEPARATOR

It removes both water and fine particulate contaminants from diesel fuel before they can reach the fuel pump and injectors, helping to prevent corrosion, abrasive wear, and injection system damage. You replace it as part of regular fuel system maintenance—typically when the filter becomes loaded with debris or the water collection bowl needs draining. This filter is built for high-pressure fuel systems operating up to 60,000 psi and provides 10-micron absolute filtration to keep modern engines running cleanly.
