Product Overview – Fleet Guard Fuel Water Separator WG9925551112-FS20156

The WG9925551112-FS20156 fuel water separator is a precision-engineered filtration component designed specifically for SINOTRUK HOWO heavy-duty trucks. It removes water and particulate contaminants from diesel fuel, ensuring clean fuel reaches the injection system for optimal combustion and engine protection. This separator is manufactured to exacting OEM tolerances, ensuring a perfect fit and reliable performance in all operating conditions.

The separator employs a multi-stage filtration process: first, a coalescing media causes water droplets to merge and separate from the fuel; then, a secondary filter captures solid particles down to 10 microns. The water collects in a transparent bowl with a drain valve for easy removal. The robust housing is made from corrosion-resistant materials, capable of withstanding fuel system pressures and temperature variations. A built-in heater option (available on some variants) prevents wax formation in cold climates.

Investing in the genuine WG9925551112-FS20156 fuel water separator ensures that your truck maintains clean, water-free fuel, reduces injector wear, improves combustion efficiency, and extends the service life of the entire fuel system. It is the preferred choice for fleet operators and workshops that demand uncompromised quality and reliability from their fuel filtration components.
