OEM direct replacement • Multi-layer synthetic media • Water separation • High dirt-holding capacity
The 1770A338 Fuel Filter is a critical component of the diesel fuel supply system, responsible for removing harmful contaminants and separating water from the fuel before it enters the high-pressure injection pump and injectors. Engineered for SINOTRUK Howo trucks, this filter is a direct OEM replacement that guarantees correct fit, high filtration efficiency, and reliable water separation. Manufactured to the original specifications, it ensures a seamless integration with the existing fuel system.
The filter element consists of a multi-layer synthetic media specially designed to capture particles as small as 2–3 microns while efficiently coalescing water droplets. The media is pleated to maximize surface area, providing extended service life and high dirt-holding capacity. The filter is housed in a durable steel canister with a corrosion-resistant coating, and features a robust gasket that ensures a leak-proof seal. A built-in water drain plug allows for easy removal of accumulated water during routine maintenance.
This fuel filter is essential for protecting the fuel injection system from abrasive wear, preventing injector sticking, and ensuring optimal engine performance and fuel economy. Its robust construction and precise engineering guarantee reliable performance over extended service intervals, meeting the rigorous demands of heavy-duty trucking. It is the direct replacement you can trust to keep your SINOTRUK Howo’s fuel system clean and efficient.
The 1770A338 Fuel Filter is specifically designed for SINOTRUK Howo heavy-duty trucks, including Howo A7, T7H, T5G, and other models that utilize this filter size and configuration in their fuel system. It is compatible with the standard filter head and fuel line connections, making it the ideal replacement for maintaining fuel cleanliness and system protection.
This filter is suitable for a wide range of applications, including long-haul trucking, regional distribution, construction, mining, and agricultural operations. Its high filtration efficiency and water separation capability ensure reliable fuel system protection even under sustained heavy loads and extreme fuel conditions.
When replacing, always verify the outer diameter, inner diameter, and height to ensure a perfect match. The 1770A338 is a direct-fit component that simplifies maintenance and restores original filtration performance.
Installing the 1770A338 Fuel Filter requires standard tools and proper fuel system safety precautions. Begin by relieving fuel system pressure and placing a container underneath the filter to catch any spilled fuel. Remove the old filter using a suitable filter wrench, taking care not to damage the filter head.
Clean the filter head mounting surface and lubricate the new filter’s gasket with a thin film of clean diesel fuel. Hand-tighten the new filter until the gasket contacts the mounting surface, then tighten an additional ¾ turn (or to the torque specified in the service manual). Never overtighten, as this can damage the gasket.
After installation, prime the fuel system by cycling the ignition or using the manual primer pump, and check for leaks. Start the engine and inspect for any fuel seepage. Regular maintenance includes replacing the filter at the manufacturer’s recommended intervals, and draining any accumulated water from the filter bowl (if equipped) more frequently in humid conditions. Always replace with a new OEM filter to ensure continued protection.
With proper installation and regular replacement, this fuel filter will provide years of reliable fuel system protection.
This fuel filter is manufactured in an ISO 9001-certified facility using premium filtration media and high-quality materials. The media is tested for filtration efficiency, dirt-holding capacity, and water separation performance to ensure it meets or exceeds OEM specifications. Each filter is inspected for dimensional accuracy, seal integrity, and structural soundness.
We perform 100% visual inspection on every filter and conduct random sample testing for burst pressure, thermal stability, and fuel compatibility.
