Fuel filter (FS1003)

Rotating type fuel filter and water separator
FS1003 is a screw-type fuel/water separator designed by Fleetguard for heavy-duty diesel engines such as those from Cummins. Its core feature is 10-micron precision filtration and efficient water separation, which protects the high-pressure oil pump and fuel injectors. It is the mainstream original factory filter for heavy trucks and construction machinery.
Type: Diesel fuel / water separator (rotating type) Size:
Outer diameter: 93.73 mm (≈ 3.69 in)
Height: 248.67 mm (≈ 9.79 in)
Thread: 1"-14 UNS-2B (standard interface)
Structure: Metal casing + composite filter material + bottom drainage valve + sealing ring (included)
Weight: Approximately 0.45 kg
Maintenance Points
Replacement Cycle: 20,000 - 40,000 kilometers (depending on the oil type and operating conditions).
Daily Inspection: Check the bottom water collection cup. Drain water once every 5,000 kilometers to prevent overflow.
Installation: Apply clean diesel to the sealing ring, tighten with a torque of approximately 35 - 40 N·m, to prevent leakage and air intake.


Core technical parameters (original factory standard)
1. Particle filtration (SAE J1985)
Filtering accuracy: 10 microns (absolute)
Filter efficiency: 98.7% (≥10 μm particles)
Filter material: StrataPore® composite deep media (patented), multi-layer gradient structure, large pollutant capacity, low pressure difference, strong resistance to moisture
2. Water separation (key performance)
Free water removal rate: 95%
Emulsified water removal rate: 95%
Principle: The coalescence layer aggregates tiny water droplets into large droplets, which fall to the bottom water reservoir under gravity, and are periodically discharged by the drainage valve
3. Pressure resistance and sealing
Maximum working pressure: 4.8 bar (72 psi)
Burst pressure: ≥10 bar (145 psi)
Sealing ring: Oil-resistant nitrile rubber, anti-aging, leak-proof, and air-proof
