The Wix 33899 Fuel/Water Separator is a heavy-duty cartridge designed to meet two-element fuel filtration needs on 2003-2007 6.0L diesel applications including select Ford Super Duty trucks, Excursion, LCF, Workhorse chassis, and International CF500/CF600 series. It serves as an OEM replacement for originals like Ford part 3C3Z-9N184-CA and Motorcraft FD-4604, replacing both fuel water separator and secondary particulate filter in the system.
Constructed with an enhanced cellulose media that is hydrophobic and chemical-resistant, it features a metal-free cartridge style. The filter is 4.240 inches tall, 3.335 inches outer diameter (top & bottom), with a closed top and a bottom inner diameter of 1.570 inches. All end caps, center tube, and sealing components are built for strength and corrosion resistance.
In real-world usage, this filter efficiently removes water and harmful contaminants from diesel fuel, protecting injectors, pump elements, and downstream components while helping prevent water-induced corrosion and performance issues. It is intended for severe duty and is an OEM direct fit to restore original filtration performance without modifications.
