The 40050800128 Fuel Filter / Filter Element, Water Separator is a premium dual‑function replacement cartridge engineered for the diesel fuel systems of SINOTRUK Howo heavy‑duty trucks, combining high‑efficiency particle filtration with advanced water separation to ensure clean, dry fuel delivery for optimal engine performance and protection. As a trusted supplier of genuine Sinotruk howo parts, we offer this OEM‑grade filter element and water separator as a direct replacement for the original factory cartridge. The 40050800128 fuel filter element effectively captures particles down to 4 microns while separating up to 95% of free water, protecting injectors and pumps from premature wear, even under the most severe hauling and construction conditions.
Engineered with a high‑density synthetic fiber coalescing media and a robust metal support core, the 40050800128 fuel filter element delivers exceptional filtration efficiency, high dirt‑holding capacity, and superior water separation. Its advanced pleat design maximizes surface area, extending service intervals and maintaining low flow restriction throughout the element’s life, ensuring a consistent supply of clean, water‑free fuel to the engine for reliable operation.
OEM 40050800128 • Fuel filter & water separator • 4‑micron efficiency • Coalescing media • Direct OEM fit
The 40050800128 is a premium dual‑function fuel filter element and water separator designed specifically for the cartridge‑type fuel filter housings of SINOTRUK Howo trucks, including the popular A7, T7H, and mixer chassis, as well as other heavy‑duty models that require this element specification. This combined component 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, corrosion, premature wear, and costly repairs.
The 40050800128 fuel filter element features a high‑quality synthetic fiber coalescing media that provides excellent filtration efficiency, high dirt‑holding capacity, and superior water separation performance. The media is treated with a hydrophobic coating that enhances water separation, allowing water droplets 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 support core ensures structural integrity and prevents media collapse under pressure.
This element is designed to fit precisely into the factory fuel filter housing, replacing the original cartridge. Its advanced design incorporates a bypass valve interface that ensures continuous fuel flow even if the element becomes fully loaded, preventing engine fuel starvation and potential damage. The element is also compatible with the housing’s water‑in‑fuel sensor port for real‑time monitoring of water accumulation.
Common symptoms of a restricted or water‑saturated fuel filter element include loss of power, rough idling, hard starting, black smoke from the exhaust, and decreased fuel economy. Replacing the element with the 40050800128 restores proper fuel flow, protects the injection system, and ensures optimal combustion efficiency. This OEM‑spec dual‑function element is the ideal choice for routine maintenance and emergency replacements.
Whether you are performing scheduled servicing or addressing a fuel‑related performance issue, the 40050800128 Fuel Filter / Filter Element, Water Separator delivers the reliability, filtration performance, water separation, and durability that SINOTRUK Howo professionals demand.
The 40050800128 fuel filter element and water separator is specifically designed for SINOTRUK Howo trucks equipped with cartridge‑type fuel filter housings that incorporate water separation functionality, including the popular A7, T7H, and mixer chassis, as well as other heavy‑duty models that use this element specification. It is a direct OE replacement and is fully compatible with all factory filter housings, water drain valves, and mounting interfaces.
This dual‑function element 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 40050800128 provides the combined filtration and water separation needed to keep the fuel system clean, dry, and reliable.
When replacing this element, it is recommended to inspect the fuel lines, primer pump, and filter housing for signs of contamination or damage. The 40050800128 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 40050800128 simplifies inventory management and ensures the correct dual‑function element is available for scheduled services. Always verify the element dimensions on your specific truck to confirm compatibility, though the 40050800128 is the standard fuel filter and water separator element for most Howo heavy‑duty applications.
Replacing the 40050800128 fuel filter element and water separator 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 housing to catch any spilled fuel.
Remove the housing cover or cap according to the vehicle’s service manual. Carefully withdraw the old filter element, taking note of its orientation and the position of any seals or O‑rings. Clean the inside of the housing thoroughly, removing any sludge or debris. Inspect the housing O‑ring or seal and replace if damaged.
Install the new 40050800128 filter element into the housing, ensuring it is properly seated and aligned with the locating features. Replace the cover or cap, tightening to the manufacturer’s specified torque. 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 housing.
For maintenance, replace this dual‑function element 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 housing drain valve – this should be done weekly or whenever the water‑in‑fuel warning light illuminates. Keep a log of element changes to track maintenance schedules and ensure optimal fuel system protection.
The 40050800128 fuel filter element and water separator is manufactured in an ISO 9001‑certified facility using advanced pleating, coalescing, and bonding technologies. The synthetic filter 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 metal support core and end caps are formed from high‑grade steel with a corrosion‑resistant coating.
Each element undergoes rigorous quality control checks, including media integrity testing, water separation verification, dimensional checks, and flow testing. Random samples from each production batch are subjected to endurance testing on a fuel system test bench to validate filtration performance, water separation efficiency, and structural durability over the element’s service life.
