The 40050800062 Fuel Separator Filter is a high‑efficiency separation and filtration component designed for the diesel fuel systems of SINOTRUK Howo heavy‑duty trucks, ensuring clean, water‑free fuel delivery and optimal engine protection. As a trusted supplier of genuine Sinotruk howo parts, we offer this OEM‑grade fuel separator filter as a direct replacement for the original factory unit. The 40050800062 fuel separator filter delivers superior water separation and particulate removal, protecting injectors and pumps from premature wear, even under the most severe hauling and construction conditions.
Engineered with a high‑density coalescing synthetic media and a robust, corrosion‑resistant steel housing, the 40050800062 fuel separator filter provides excellent filtration efficiency, capturing particles down to 4 microns while effectively separating up to 95% of free water from the fuel. Its advanced pleat design and water‑repellent layer maximize separation performance, extending service intervals and maintaining low flow restriction throughout the filter’s life, ensuring consistent fuel flow to the engine.
OEM 40050800062 • Fuel water separation • 4‑micron efficiency • Coalescing media • Direct OEM fit
The 40050800062 is a premium fuel separator filter designed specifically for SINOTRUK Howo trucks, including the popular A7, T7H, and mixer chassis, as well as other heavy‑duty models that require this filter specification. This filter plays a vital role in protecting the high‑pressure fuel pump and injectors from both abrasive particles and water contamination, which are common causes of injector sticking, premature wear, and costly repairs.
The 40050800062 fuel separator filter features a high‑quality coalescing synthetic media that combines mechanical filtration with a water‑repellent treatment. This design effectively separates water droplets from the fuel, allowing them to coalesce and drop to the bottom of the filter housing, where they can be easily drained via the integrated drain valve. Its robust metal casing is internally coated to resist corrosion and is designed to withstand fuel system pressures up to 12 bar.
A reliable bypass valve is incorporated to ensure continuous fuel flow in the event of filter clogging, preventing engine fuel starvation and potential damage. The filter also includes a water‑in‑fuel sensor port (compatible with OEM sensors) for real‑time monitoring of water accumulation, giving drivers and fleet managers early warning of potential issues.
Common symptoms of a restricted or water‑saturated fuel separator filter include loss of power, rough idling, hard starting, black smoke from the exhaust, and decreased fuel economy. Replacing the filter with the 40050800062 restores proper fuel flow, protects the injection system, and ensures optimal combustion efficiency. This OEM‑spec filter is the ideal choice for routine maintenance and emergency replacements.
Whether you are performing scheduled servicing or addressing a fuel‑related performance issue, the 40050800062 Fuel Separator Filter delivers the reliability, separation performance, and durability that SINOTRUK Howo professionals demand.
The 40050800062 fuel separator filter is specifically designed for SINOTRUK Howo trucks equipped with common‑rail or unit‑injector fuel systems, including the popular A7, T7H, and mixer chassis, as well as other heavy‑duty models that use this filter specification. It is a direct OE replacement and is fully compatible with all factory filter heads, fuel lines, and sensor ports.
This filter is ideal for applications where fuel quality may vary, such as construction sites, mining operations, and long‑haul transport. In these environments, water and particulates in diesel fuel are common and can cause serious injector and pump damage. The 40050800062 provides the filtration and water separation needed to keep the fuel system clean and reliable.
When replacing the fuel separator filter, it is recommended to inspect the fuel lines, primer pump, and filter housing for signs of contamination or damage. The 40050800062 is compatible with standard diesel and biodiesel blends up to B20, offering flexibility for fleet operators.
For fleets with multiple Howo trucks, standardizing on the 40050800062 simplifies inventory management and ensures the correct filter is available for scheduled services. Always verify the filter thread and dimensions on your specific truck to confirm compatibility, though the 40050800062 is the standard separator filter for most Howo heavy‑duty applications.
Replacing the 40050800062 fuel separator filter is a routine maintenance task that can be performed by most technicians using standard hand tools. Begin by relieving the fuel system pressure and placing a container under the filter to catch any spilled fuel.
Remove the old filter by turning it counterclockwise with a filter wrench. Clean the mounting surface on the filter head, ensuring the old gasket is completely removed. Apply a thin film of clean diesel fuel to the new filter’s gasket to ensure a proper seal. Screw the new 40050800062 filter onto the head until the gasket contacts the sealing surface, then tighten an additional ¾ to 1 full turn (or to the manufacturer’s torque specification of 20‑25 Nm).
After installation, prime the fuel system using the primer pump until fuel flows from the vent screw, then close the vent. Start the engine and check for leaks around the filter. Open the water drain valve briefly to purge any air and ensure proper water separation function.
For maintenance, replace the fuel separator filter at every recommended service interval, typically every 15,000‑20,000 km for heavy‑duty applications, or more frequently if operating in areas with poor fuel quality. Regularly drain accumulated water from the filter using the drain valve – this should be done weekly or whenever the water‑in‑fuel warning light illuminates. Keep a log of filter changes to track maintenance schedules.
The 40050800062 fuel separator filter is manufactured in an ISO 9001‑certified facility using advanced pleating and bonding technologies. The coalescing media is sourced from leading global suppliers and is tested for efficiency, dirt‑holding capacity, and water separation performance according to SAE J1488 standards. The steel housing is formed from high‑grade cold‑rolled steel and coated with a durable anti‑corrosion layer.
Each filter undergoes rigorous quality control checks, including media integrity testing, water separation verification, burst pressure testing, and leak testing under vacuum and pressure. Random samples from each production batch are subjected to endurance testing on a fuel system test bench to validate filtration performance and structural durability over the filter’s service life.
We back the 40050800062 with a comprehensive 12‑month warranty against material and workmanship defects. Our commitment to quality ensures that every filter delivers the same level of protection and performance as the original equipment, giving you confidence in your fuel system’s reliability.
