When diesel fuel sits in storage tanks, it naturally separates and accumulates water that can wreak havoc on your engine's fuel system. The WIX 33402 Heavy Duty Spin On Fuel Water Separator is engineered to remove those damaging water contaminants before they ever reach your injectors and fuel pump, ensuring your engine runs clean and efficient.
Water contamination isn't just inconvenient—it's potentially catastrophic for diesel engines. Even small amounts can cause injector damage, microbial growth that clogs filters, and corrosion throughout the fuel system. That's why professional mechanics and serious truck owners insist on reliable water separation technology like what WIX has been providing for decades.
The 33402 model features a robust construction designed to handle the toughest conditions. Unlike cheaper alternatives that may fail under pressure, this WIX separator maintains consistent performance whether you're running in extreme heat, cold, or high-moisture environments. The spin-on design means you can install it yourself with basic tools and replace it quickly during routine maintenance.
Whether you're a long-haul trucker, construction equipment operator, or diesel enthusiast, this filter delivers where it matters most. It's particularly valuable for those who store fuel for extended periods or operate in areas with high humidity. The visual water indicator (when equipped) lets you know exactly when it's time for a change, preventing costly breakdowns and ensuring your engine stays protected around the clock.
Invest in the protection your diesel engine deserves—WIX has been a trusted name in filtration since 1939, and the 33402 continues that legacy of quality and reliability in every component.
