The A3000-1105020 fuel filter WS features a multi‑layer media composed of cellulose and synthetic fibers that provide excellent filtration efficiency (98% at 5 microns) while maintaining high flow rates. The media is pleated to maximize surface area, ensuring long service intervals even in contaminated fuel conditions. An integrated water separator with a hydrophobic screen effectively removes emulsified water, protecting the injection system from corrosion and cavitation. The filter housing is constructed from heavy‑gauge steel with a corrosion‑resistant epoxy coating, ensuring durability under the vehicle.
Each A3000-1105020 filter is 100% tested for burst pressure (minimum 20 bar) and is equipped with a built‑in drain valve for easy water removal during maintenance. The filter head includes a primer pump (on applicable models) to facilitate bleeding after filter changes. All sealing surfaces use high‑quality nitrile rubber O‑rings that resist biodiesel blends. This meticulous engineering ensures that the filter delivers reliable protection against abrasive particles and water, extending the life of fuel injectors and high‑pressure pumps.

The A3000-1105020 fuel filter WS is a direct OEM replacement installed between the fuel tank and the high‑pressure pump. It is used on Howo trucks equipped with WD615, MC11, MC13, and D10 engines. The filter’s primary role is to capture particles (>5 microns) and separate water before the fuel reaches the precision injection components. This pre‑filtration dramatically extends the life of the injectors and protects the fuel system from abrasive wear.
In chassis applications, the fuel filter is often mounted on the frame rail, exposed to road spray and vibration. The genuine A3000-1105020 is built with a robust steel housing and vibration‑damped mounting to withstand these harsh conditions. Regular replacement of this filter is essential for maintaining fuel system reliability; a clogged or water‑logged filter can lead to power loss, hard starting, and injector failure. Using a genuine filter ensures that the fuel system receives the level of protection designed by SINOTRUK engineers.
Always replace the fuel filter at the recommended interval (every 30,000 km or annually). After replacement, prime the system using the built‑in primer pump to remove air before starting the engine.
Correct installation of the A3000-1105020 filter is essential to ensure proper fuel flow and sealing. Follow these steps:
Relieve fuel system pressure by loosening the fuel cap. Place a container under the filter to catch spilled fuel. Unscrew the old filter by hand or with a filter wrench.
Apply a thin film of clean diesel fuel to the new filter’s O‑ring. Screw the filter onto the head until the gasket contacts, then tighten an additional 3/4 turn by hand. Do not overtighten.
Use the primer pump (if equipped) to fill the filter and bleed air from the system. Start the engine and check for leaks. Run at idle for a few minutes to ensure stable operation.
A clogged or water‑logged fuel filter can cause performance issues. Common signs that replacement is needed include:
If any of these symptoms are observed, immediate replacement with a genuine A3000-1105020 filter is recommended. Continuing to operate with a restricted filter can starve the injection pump of fuel, leading to premature wear and costly repairs.
The high‑efficiency media traps particles as small as 5 microns, protecting injectors and pumps from abrasive wear.
The integrated water separator removes emulsified water, preventing corrosion and cavitation in the injection system.
Pleated media provides large dirt‑holding capacity, reducing the frequency of filter changes and lowering maintenance costs.
To maximize the service life of your A3000-1105020 fuel filter, follow these best practices:
By adhering to these guidelines, you ensure that the A3000-1105020 filter performs optimally throughout its intended service interval.
Aftermarket fuel filters often use substandard media with lower efficiency and poor water separation, allowing contaminants and water to reach the injection system. The genuine A3000-1105020 is manufactured to the exact specifications of the original equipment, using certified media and rigorous testing. Each filter is tested for burst pressure, filtration efficiency, and water separation, guaranteeing that it will perform exactly as the original part.
By choosing authentic SINOTRUK HOWO parts, you protect your investment and ensure your truck maintains its fuel efficiency and reliability. The Sinotruk howo parts catalog includes a full range of fuel system components engineered for maximum durability. For fleet managers and owner‑operators who demand the best, the genuine A3000-1105020 is the only responsible choice.
The A3000-1105020 fuel filter WS is used across a wide range of Howo models: T7H, A7, and classic Howo‑7 series equipped with WD615, MC11, MC13, and D10 engines. It fits both spin‑on and cartridge‑type filter heads. Always verify the thread size and O‑ring dimensions using the service manual.
Each A3000-1105020 is individually packaged in a sealed box with a protective plastic bag. The package includes the filter only; the filter head and mounting hardware must be ordered separately if needed.
Production of the A3000-1105020 takes place in IATF 16949 certified facilities, using automated pleating and assembly lines. Statistical process control ensures that every filter meets the stringent requirements for efficiency, flow, and burst pressure. Every batch is accompanied by a material certificate and test report, guaranteeing that the filters delivered are identical to those fitted on new Howo trucks at the factory.
