FAW Jiefang J6P Diesel Fuel Filter Element

1. Overview​

The FAW Jiefang J6P Diesel Fuel Filter Element 1105050-2007A is a dedicated filtration component engineered exclusively for FAW Jiefang J6P heavy-duty diesel trucks—one of the core models in China’s long-haul logistics and heavy-cargo transportation market. As a key part of the J6P’s fuel supply system, this filter element is designed to match the performance characteristics of the vehicle’s matched diesel engines (such as the CA6DM2, CA6DM3 series with 420-550 HP output). It strictly adheres to FAW’s OEM standards, ensuring it meets the high requirements for fuel purity in the J6P’s common-rail injection system, effectively protecting the engine from impurity damage and maintaining stable power output during long-distance, high-load operations.​

2. Vehicle & Engine Compatibility​

• FAW Jiefang J6P Series: Specifically adapted to FAW Jiefang J6P heavy-duty trucks, covering 4×2, 6×4, 8×4 and other mainstream configurations. These models are widely used in inter-provincial long-haul logistics, bulk cargo transportation (such as coal, grain), and engineering support—scenarios that place high demands on engine reliability and fuel efficiency. The 1105050-2007A filter element is the original-equipment choice for J6P vehicles off the production line, ensuring perfect fit with the vehicle’s fuel tank, fuel pump, and injection system.​

• Engine-Specific Matching: Tailored to FAW’s self-developed CA6DM2 (11L displacement) and CA6DM3 (13L displacement) diesel engines. These engines feature high-pressure common-rail systems (maximum injection pressure up to 2000 bar) that are extremely sensitive to fuel impurities. The 1105050-2007A filter element matches the engine’s fuel flow rate (120-150 L/h) and working pressure (0.12-0.18 MPa), avoiding issues like insufficient fuel supply or injection system wear caused by mismatched universal filters.​

• Genuine Part Identification: Marked with the official part number 1105050-2007A and FAW’s anti-counterfeiting logo, it is compatible with FAW Jiefang’s official after-sales system. Users can verify authenticity through FAW’s official APP or after-sales service network, ensuring they avoid the risks of using counterfeit filters (such as engine failure or shortened service life).​

3. Working Principle​

The 1105050-2007A fuel filter element adopts a two-in-one integrated filtration structure (impurity filtration + water separation), targeting the two major threats to the J6P’s engine: solid impurities and water in diesel fuel:​

1. Impurity Filtration Layer: The outer core uses high-density wood pulp filter paper with a gradient pore structure. The outer layer (pore size 8-10 microns) traps large impurities such as rust from the fuel tank and sand particles in low-quality diesel; the inner layer (pore size 2-3 microns) captures tiny contaminants like colloids and micro-metal shavings. This two-stage filtration ensures that over 99.5% of impurities are removed, preventing clogging and wear of the engine’s injectors and fuel pump.​

2. Water Separation Layer: The middle of the filter element is embedded with a hydrophobic polyester membrane. When diesel containing water droplets passes through, the membrane repels water (utilizing the difference in surface tension between oil and water), allowing water to condense into small droplets and settle at the bottom of the filter housing. The housing is equipped with a water drain valve, enabling users to discharge accumulated water regularly and avoid corrosion of the fuel system and engine cylinder walls.​

3. Pressure Stabilization Protection: The filter element is designed with a built-in pressure relief valve (set pressure 0.2 MPa). When the filter element is partially clogged (e.g., due to prolonged use in harsh environments), the valve opens to ensure continuous fuel supply to the engine, preventing sudden power loss during driving—critical for safety in long-haul transportation.​

4. Key Features and Benefits​

• OEM-Grade Filtration Reliability: As a genuine FAW part, the 1105050-2007A filter element undergoes strict testing (including 100-hour continuous filtration efficiency tests and 5000-cycle vibration tests) before leaving the factory. In actual use, J6P vehicles equipped with this filter element have a 40% lower incidence of fuel system failures compared to those using aftermarket filters, significantly reducing maintenance downtime.​

• High Adaptability to Harsh Environments: The filter paper is treated with a special resin coating, making it resistant to high temperatures (up to 130°C) and low temperatures (down to -40°C). This ensures stable filtration performance in extreme climates—whether in the high-temperature deserts of western China or the frigid northeast winter—and avoids filter paper deformation or cracking caused by temperature fluctuations.​

• Long Service Life, Low Replacement Cost: The high-capacity filter paper (filter area up to 0.8 m²) can trap more impurities, extending the service life to 25,000-30,000 kilometers under normal conditions. For J6P users who drive 100,000+ kilometers annually, this reduces the number of filter replacements, lowering annual maintenance costs by 15-20% compared to low-quality filters.​

• Easy Maintenance: The filter element features a snap-on installation design that matches the J6P’s original filter housing. No special tools are required—users can complete replacement in 5-8 minutes, saving time during routine maintenance stops at highway service areas.​

5. Maintenance and Replacement​

• Regular Inspection:​

• Check the water level indicator on the filter housing weekly. If the red water level line is visible (indicating water accumulation exceeding 50 ml), open the drain valve at the bottom to discharge water until clean diesel flows out.​

• Every 10,000 kilometers, visually inspect the filter element through the transparent housing (if equipped). If the filter paper appears dark brown or has obvious impurity deposits, replace it in advance.​

• Replacement Interval:​

• Under normal conditions (using national standard No. 0/-10/-20 diesel and regular fuel tank cleaning), replace the filter element every 25,000-30,000 kilometers.​

• In harsh environments (e.g., mining areas with high dust, regions with frequent use of non-standard diesel), shorten the interval to 15,000-20,000 kilometers to avoid premature engine damage.​

• Installation Precautions:​

1. Before replacement, turn off the engine and release the fuel pressure (by pressing the manual pump on the filter housing 2-3 times) to prevent fuel leakage.​

2. Ensure the filter element’s sealing ring is intact. Apply a small amount of clean diesel to the sealing ring before installation to ensure a tight seal and avoid air entering the fuel system (which could cause difficult starting).​

3. After installation, press the manual pump 5-8 times until resistance is felt, then start the engine and idle for 3-5 minutes. Check for fuel leakage at the housing connection—if leakage occurs, re-tighten the housing clamp.​

6. Conclusion​

The FAW Jiefang J6P Diesel Fuel Filter Element 1105050-2007A is a “core protector” for the J6P’s fuel system and engine. By integrating FAW’s deep understanding of heavy-duty truck engines with advanced filtration technology, it not only meets the strict requirements of the J6P’s high-performance engine but also helps users reduce maintenance costs and improve transportation efficiency. For FAW Jiefang J6P owners and fleet managers, choosing this genuine filter element is a cost-effective way to ensure long-term, trouble-free operation of their vehicles and protect their valuable transportation assets.
