4070801 FILTER FUEL FS1003 Wear Resistant Heavy Machinery Fuel Filter Element

Product Overview

4070801 fuel filter, also known as FS1003 (FILTER,FUEL), is a high-performance fuel filtration and water separation component designed for heavy-duty diesel engines and engineering mechanical equipment. As a core protective part of the engine fuel supply system, it deeply filters solid impurities such as dust, metal particles and carbon deposits in diesel, and efficiently separates mixed moisture in fuel. This fuel filter effectively solves common engine faults such as fuel injector clogging, poor atomization, insufficient power output, excessive exhaust smoke and fuel system corrosion caused by unfiltered dirty fuel. It keeps the fuel supply system clean and stable, and extends the service life of engine precision fuel injection components under long-term high-load operation.

Core Product Advantages

1. High-Density Composite Filter Media: Adopts multi-layer high-precision filter paper composite structure, with uniform filter pore size and strong adsorption capacity. It can intercept tiny fuel impurities effectively, providing excellent deep filtration performance while ensuring smooth fuel circulation.

2. Efficient Fuel-Water Separation Performance: Optimized hydrophobic and oil-absorbing filter material formula, it accurately separates free water and emulsified water in diesel fuel, avoids water entering the combustion chamber and fuel system corrosion, and protects precision injectors and pump cores.

3. High Pressure & Seismic Resistance: Reinforced integral shell structure with good compression resistance and seismic stability. It adapts to fluctuating fuel pressure and long-term vibration of engineering equipment, no shell deformation, leakage or filter element damage.

4. High & Low Temperature Durability: Stable filtration performance in extreme working environments of -40℃ to +130℃. The filter material does not soften, deform or lose filtration efficiency under high temperature, and remains tough and unbreakable in low temperature environments.

5. Anti-Corrosion & Leak-Proof Design: Premium rubber sealing ring and anti-rust shell treatment ensure tight fitting without fuel leakage. Resists corrosion of diesel fuel and chemical substances, adapting harsh working conditions of construction sites and mining environments.

6. Standard Dual Model Specification: Strictly follows 4070801 and FS1003 universal size standard, with overall dimension 28.4cm*14cm*13.8cm and weight 1.164KG. Perfectly matches heavy-duty engine fuel system installation structure for plug-and-play replacement.

7. Strict Factory Quality Inspection: Finished filters pass filtration efficiency test, pressure resistance test and leakage test, with stable batch quality for equipment daily maintenance, engine overhaul and fleet bulk procurement.
