Sinotruk HOWO Fuel Water Separator VG1092080052 (Replaces PL421) – Primary Diesel Filter

Bad fuel is the number one enemy of heavy-duty trucks. The VG1092080052 Fuel Filter (functionally equivalent to the PL421) is the primary line of defense for your Sinotruk HOWO fleet. Installed before the lift pump, this robust separator removes water and coarse debris from the diesel tank before they can reach your engine’s sensitive components.

Designed for the harsh operating conditions often found in construction and mining sites, this filter features a high-capacity bowl to trap water condensate. If your truck is experiencing rough idling or difficulty starting, a clogged pre-filter is often the culprit. Replacing it with this genuine OEM specification part ensures your Weichai engine receives a steady flow of clean fuel, preventing costly corrosion in the injection system.
